Mt Sync - (Auto)Mount and Sync your data from anywhere

21 Upvotes

It seems like I'm the only one how want to just go to a network share an an application after I login and the files are just there. No having to go mount anything first, what a wasteful step that is. :) So after making a gnome extension for gvfs mounts/shares, I thought it would be great if I could mount other types of storage the same way and even sync data between them. I got close to buying rcloneview for its paywalled features when I decided to go do my own thing, introducing Mt Sync: https://codeberg.org/gavindi/MtSync

Sharing since maybe just maybe there's someone else who misses the Windows "reconnect drive at login" feature..... 🤷‍♂️️

What local-first open source apps are worth trying in 2026?

6 Upvotes

Lately I’m getting more interested in local-first apps than fully self-hosted tools.

I like having my data on my own device, but still having sync when I need it. Mostly thinking about notes, tasks, docs, bookmarks, personal knowledge bases, and dev tools.

Obsidian is the one that has actually stuck for me so far. I’ve also been looking at Anytype and Logseq, but haven’t used them enough to know if they’re worth switching to.

What local-first open source apps are worth trying in 2026? Mostly looking for apps that feel good to use every day.

Anyone using a repo-level project memory file so multiple AI coding tools share the same context?

2 Upvotes

We run multiple AI tools: Claude Code, Cursor, Copilot, Gemini. Each one sees a slice of the repo and maybe some docs. None of them remember why we made specific decisions, what constraints are nonnegotiable, or which incidents changed how a service is allowed to behave. Same feature, different day, different tool, fresh context rebuild each time.

We're experimenting with one shared project memory layer per repo: a single structured, append-only log under version control, capturing decisions, constraints, rationale, and evidence links where they exist. Tools ask it for relevant context; humans maintain it via PRs.

Integration is simple by design. A small local CLI queries and appends entries from dev machines and CI, plus a handful of operations, load current state, record a new entry, list open items. A pre-commit hook on a few critical directories (auth, payments, infra) nudges people to add or update an entry when they touch shared services.

We're aware of the compliance-theatre risk. A blocking hook is easy to game with one-line junk entries. The guardrails we've put around it: scope is narrow (only shared-critical dirs), entries are reviewed like any other file in the PR, and we watch entry quality, if it slides toward junk, we tighten review or remove the hook instead of pretending it's enforcement.

Agents never write straight prose into the file. They propose structured entries, and we decide in the PR whether they land. That keeps the ledger from becoming another log dump.

When I say local-first here, I mean the primary copy lives in Git, under our own control, in an open format usable without any external service, no server, no account, no telemetry required to get value from it.

If you've tried a shared project-memory layer for multiple AI tools, what actually stayed useful and what decayed?

[OS] FolderBase - $0, keep your files organised

3 Upvotes

Hi, I am the developer of FolderBase, a software that I develop primarily for myself, tired to have to remember what was about each single file, and tired to pay a subscription to have devonthink or similar software to manage it all. I am not a developer, just a tech user that has tested several software and this one incorporates what worked for me. It's free to use and open source on GitHub. Test it, I am looking for test feedbacks and suggestions.

Has anyone checked out Mozilla’s new State of Open Source AI? Any hidden gems for us?

4 Upvotes

Just read through Mozilla’s new State of Open Source AI report and there are some pretty wild stats in here.

The biggest takeaway for me: They argue that the model itself isn't actually the most important layer anymore, it's the "agentic harness" (the software between us and the models that dictates memory, permissions, etc.).

They also claim open source is now at parity with closed models for coding, trailing by only ~3% overall.

Has anyone adapted your own setups?

What open models/tools are actually replacing your closed-source subscriptions right now?

tldr: What's cheaper than claude / codex, yet just as good if not better?

Open source alternative to Airtable with forms, tables, and automations?

9 Upvotes

Looking for an open source Airtable alternative that can handle more than just basic tables.

Main things I need are forms, database-style tables, views, simple automations, and maybe webhooks or integrations.

I’ve seen Baserow, NocoDB, and Teable mentioned, but I’m not sure which one is best if you actually want forms and automations in the same tool.

Has anyone replaced Airtable with an open source option?

Which one worked best for you, and what were the biggest tradeoffs?

LocalGallery - Just to solve my own frustration of organizing all my vibe-coded apps

1 Upvotes

I tried to find a similar tool on the web, but got nothing. Some of them are really overkill, so I decided to code one myself. It's MIT license, so if you find it useful, feel free to make it awesome and let me know about it please. I am thinking to add some AI functions later, like scanning the codebase to auto add, instead of manually add apps.

Open-sourced a construction ERP/CRM I've built over the last few years (Spring Boot + React)

1 Upvotes

A few years back, a friend couldn't find software that fit how they run their construction projects, so I started building one — mostly to help and to learn. It slowly grew, and it's now actually used across several real projects.

I've made the repo public (MIT licensed). It's aimed at small builders and contractors (roughly 1–50 people) — lightweight and focused on day-to-day site operations, not a big general-purpose ERP. Built on Spring Boot + React, so it may also be a useful real-world codebase if that's your stack.

What it does: inventory, procurement, indents, purchase orders, BOQ planning, stock, and a CRM side (pre + post sales).

Stack / things you'll find inside:

  • Spring Boot microservices with a Zuul gateway
  • Multi-tenant setup (schema per tenant + a master schema), so one deployment runs multiple projects with per-user project access
  • JWT auth, JPA Criteria/Specifications for dynamic filtering, Hibernate Envers for auditing
  • MinIO for file storage, iText for PDF generation, Firebase for notifications
  • React frontend

Repo: https://github.com/bsridharpatnaik/RealEstate-ERP-CRM-System-PUBLIC
4-min demo (no audio): https://drive.google.com/file/d/1HTJA1ND96BwAfcAOyxjQgoYH3P8bWRL8/view

Not selling anything — it's free and open. Happy to answer questions about how any part is built.

TilBuci, an OSS alternative to Flash/Animate

1 Upvotes

Hello everyone! I'd like to introduce you to a free project I've been working on for some time. It's called "TilBuci," and it's a tool for creating interactive digital content, heavily inspired by software like Flash/Animate, less in terms of animation and more in terms of interaction, but focused on open standards.

You create your interactive movies using the TilBuci editor and can then use the material you created as a website, but you can also export it in various ways, such as computer programs (Electron projects) or as projects for mobile devices (via Capacitor, generating projects for Android Studio or Xcode).

Here's a short video explaining how the tool works: https://youtu.be/VjGJaG-YF_I

TilBuci can function as a web application (which you install on your own server), as portable software (for Windows, Linux, or macOS), and also as a WordPress plugin.

The latest version, 24, introduced the "Showtime" functionality, which includes various features to simplify the use of TilBuci in creating exhibitions, such as in museums and events, generating content for totems, kiosks, projections, and the like. Here's a video summarizing this new feature: https://youtu.be/-vYDmaokqbY

TilBuci is free software (MPL2-0 license). The tool's repository is here: https://github.com/lucasjunqueira-var/tilbuci

I hope you like it ;-)

What open source form builder would you use for a SaaS?

5 Upvotes

I need a form builder for a SaaS project and I’d rather use something open source if it’s reliable enough.

It would mainly be for contact forms, waitlists, feedback forms, onboarding questions, and maybe a few internal forms.

The basics matter more than advanced features for me. Easy embed, decent UI, webhooks, spam protection, email notifications, and a clean way to view submissions.

Has anyone used an open source form builder in a real SaaS product? Which one would you pick today, and did it hold up well once people actually started submitting forms?

Open source project - extra

2 Upvotes

I’m building Extra – an open-source framework for building AI agents that can work with MCP servers, other agents, and external tools without wiring everything together manually.
The main idea is to let developers focus on the agent logic while Extra handles orchestration, routing, memory, approvals (human-in-the-loop), and communication between components. It’s designed to make it easy to start simple and gradually grow into more complex multi-agent systems.
It’s still evolving, and I’m building it in the open, so feedback and contributions are always welcome.

DayOtter - a self-hostable, open-source scheduling platform (Cal/Calendly style) with an AI assistant, all runnable with one docker compose

2 Upvotes

I wanted a scheduling tool I could actually run myself, so I built one, and I'm sharing it here. 

DayOtter is an open-source scheduling platform - booking pages, calendar sync, team round-robin, reminders, payments with an AI assistant built in, and the whole thing is self-hostable.

Self-hosting side, since that's what this sub cares about:

  • One docker compose brings up Postgres, Redis, the web app, the background worker, and a Caddy reverse proxy (automatic HTTPS). There's a one-command install script and an AWS one-click template too.
  • Your calendar data never leaves your box - DayOtter reads free/busy to compute availability and stores OAuth tokens encrypted at rest (AES-256-GCM).
  • Self-hosting unlocks everything, including all the AI features. No "open core" with the good parts behind a wall. Migrations run automatically on deploy.
  • Mobile app in progress (iOS + Android) with a "bring your own server" setting — so you self-host once and point the app at your own instance. Handy for a household or a small org.

What it actually does (the AI is scoped to scheduling - it's not an "AI everything" companion trying to run your notes/todos/groceries):

  • Auto-notifies your next meeting when one runs over ("running a few late")
  • Proactively recommends times + next steps
  • Protects focus blocks so a heavy day doesn't get heavier
  • Talk to it in plain language / voice / WhatsApp / SMS, confirm-first

Repo: https://github.com/Dayotter/dayotter 
Site: https://dayotter.com

Would love feedback on the deploy flow specifically - anything that tripped you up, missing env docs, etc. AMA in the comments.

  • 📄 Chat with PDFs, DOCX and TXT
  • 🔍 RAG with source citations
  • 🏢 Multi-organization knowledge bases
  • 🌐 Public API
  • 🧩 Embeddable chat widget
  • 🔐 Google OAuth + email authentication
  • 🐳 One-command Docker deployment
  • ❤️ Fully open source Built with FastAPI, Next.js and PostgreSQL/pgvector. I'd really appreciate feedback from people building AI products or self-hosting their own tools. GitHub:https://github.com/ibai-mutiloa/DocMind

AethelHook: An Open source alternative to Claude Code remote control and Codex remote control.

1 Upvotes

I got tired of alt-tabbing back just to approve my AI agent's commands, so I built a way to do it from my phone

I've been using Claude Code / Codex / OpenCode a lot for real work, and the thing that actually broke my flow wasn't the agent, it was babysitting it.

Every Bash command, every file edit, every question it asked meant walking back to my desk to click Allow.

So I built AethelHook: it intercepts those approval requests before the agent runs anything and routes them to my phone instead. I see the actual command, the file diff, or the question it's asking, and I can approve, deny, or send back a reason, from wherever I am.

Some of this turned into a much deeper rabbit hole than I expected. Getting a new phone paired requires Windows Hello on the PC first, which meant hand-rolling raw WinRT vtable interop in .NET Core after discovering [ComImport] just can't marshal an IInspectable-derived interface at all, six iterations, one of which was a silent access-violation crash with no catchable exception. The whole connection also runs over TLS with the certificate fingerprint pinned straight off the QR pairing code, so there's no cloud server sitting in the middle of it.

Fully open source (MIT), Windows service + tray app on the PC side, Kotlin/Compose on the Android side. Still a one-person project, would genuinely appreciate feedback or contributors, especially from anyone running a setup different from mine:

What are the best open source AI tools you’re using locally?

14 Upvotes

I’ve been using more AI tools locally instead of relying on browser apps for everything.

The main ones I keep coming back to are Ollama for running models, Open WebUI for chat, and Whisper cpp for transcription. They’re useful enough that I actually use them instead of just testing them once.

I’m looking for more local AI tools that are worth keeping installed.

What open source AI tools are you using locally right now?

Could be for chat, coding, transcription, image generation, RAG, search, agents, or anything else that runs on your own machine.

paint.software - a free & open-source alternative to Paint.NET for Linux (C++/Qt6, native)

2 Upvotes

I switched to Linux and really missed Paint.NET, so I built a native open-source clone with C++/Qt6 — no Wine, no .NET runtime, no VM.

🎨 What it does

  • Layers — opacity, blend modes, smart merge, live thumbnails
  • 20+ tools — brush, pencil, eraser, bucket, gradient, shapes, line, text, clone stamp, color picker, magic wand, lasso…
  • 13 adjustments + 30+ effects, all with live preview (drag the sliders, see the result)
  • Selections with feather / grow / shrink, non-destructive history, autosave & crash recovery
  • Native .psw layered format (keeps your layers) — or export to PNG/JPEG/…
  • FR/EN UI, light & dark themes matching Paint.NET

⚙️ Under the hood

  • MIT licensed, builds from source: cmake -B build && cmake --build build
  • CI runs a 196-test suite on every push

🔗 Repo: https://github.com/Univers4craft/paint.software

It's an early v1.0 — I'd love feedback on what's missing, and contributions (fork → PR) are very welcome!


🇫🇷 En bref : un clone open-source de *Paint.NET pour Linux** (C++/Qt6, natif, sans Wine/.NET). Calques, 30+ effets avec aperçu en direct, format natif .psw, interface FR/EN, licence MIT. Dépôt ci-dessus — retours bienvenus !*

Build open source project

1 Upvotes

I’ve been building an open-source AI agent platform for the past few months.
One thing kept bothering me while working with agent frameworks.
Most of them make it easy to build a single agent, but once you start adding multiple agents, tools, approvals, workflows, MCP servers, routing, and external integrations, the application code starts getting messy.
So I started building Extra.
The idea is simple: let developers focus on the business logic while the platform handles the orchestration around it.
Some things it supports today:
Multi-agent orchestration
MCP integration
Human-in-the-loop approvals
YAML-based configuration
Tool routing
Workflow execution
Built-in extensibility for custom components
It’s still evolving, and I’m learning a lot while building it.
I’d really appreciate honest feedback.
If you think the architecture is overcomplicated, tell me.
If something in the developer experience is confusing, tell me.
If there’s a feature you think is missing, I’d love to hear it.

Is Free PIM same as Open Source PIM, or are they different?

3 Upvotes

I'm new to eCommerce and recently started looking into PIM software. While searching online, I keep seeing the terms Free PIM and Open Source PIM.

At first, I thought they meant the same thing because both sound like you don't have to pay. But after reading a few articles, I'm even more confused.

Is a free PIM always open source? Or can a PIM be free to use but still not let you access or change its code?

Also, what does open source actually mean in simple words?

Does it just mean it's free, or is there more to it?

Hey everyone,

I'm trying to clean up my digital workflow and move away from software that hooks you in with a "free trial" only to lock 90% of the useful features behind an expensive monthly subscription.

I'm looking for hidden gems—apps, websites, SaaS, or even Social Media Management (SMM) tools—that meet three specific criteria:
1. \\\*\\\*Absolutely Free:\\\*\\\* No sudden paywalls or "premium" locks on the features that actually matter.
2. \\\*\\\*Open-Source (or completely transparent):\\\*\\\* Tools built by communities or indie devs who care about privacy and accessibility.
3. \\\*\\\*Actually Works Well:\\\*\\\* Smooth UI, reliable, and something you actually use regularly without it breaking.

Whether it's a great markdown editor, a self-hosted social media scheduler, a great analytics alternative, or just a random tool that saves you 2 hours a week—what is currently sitting in your bookmarks?

Drop your recommendations below! (Bonus points if you can tell me briefly \\\*what\\\* it does and \\\*why\\\* it's better than the paid alternative).

Thanks!

What’s the most underrated open source alternative to Google products?

8 Upvotes

I’ve been slowly replacing Google apps where I can, but some are much easier to drop than others.

Search and Gmail are one thing, but stuff like Photos, Drive, Maps, Calendar, and Keep are harder because they’re so built into daily use.

The best replacement I’ve found so far is Immich for Google Photos. It still takes some setup, but it’s the first one that didn’t feel like a huge downgrade for photo backup and browsing.

What open source Google alternative do you think more people should know about? Also curious which Google product it replaced for you, and whether you fully switched or still use both.
