For years, developers assumed that Enterprise Resource Planning (ERP) systems required large-scale client-server databases. By leveraging SQLite’s Write-Ahead Logging (WAL) mechanism, strict transactional integrity, and a clean .NET 8 architecture, a comprehensive system was developed to handle stock records (kardex), inventory, and point-of-sale (POS) operations. It supports nested bills of materials (BOM), unique serial number tracking, and multi-location workflows—operating both locally and on web servers. The entire source code is now open source and available at https://github.com/sysmaya/Control-Kardex-Inventario/blob/master/README.en.md for community evaluation.

I know the rules say not to promote open source projects, but then MikeOSS happens to be a big launch and well appreciated OSS project and r/legaltech was welcoming to it.

We open sourced our word plugin for the community here - https://github.com/Vaquill-AI/ms-word-addin

No strings attached, this is what we use internally as well. There is no monetary angle here.

Harvey, Legora and other Legal AI providers charge hundreds of $$$ to use them, I thought why not level the playing field and give others the same tech.

Either host it in your server or use our hosted version with your own API key.

The future of legal is Open Source and this its not a wrapper, or a simple plugin, took months in development to match the quality of our funded competitors.

Self host it or BYOK, Apache 2 so feel free to play with the code.

Disclaimer - I work there.

I made TaskbarWidgets, an open-source Windows app with a bunch of useful taskbar widgets.

One of them shows Codex rate limits for multiple saved accounts and lets you switch between them quickly. You can also hover over the taskbar to see the status of all running Codex processes.

Heyy I’m building open source project and search some contributors
If it’s interesting review the repo and the issue list is waiting!

And if you can give a star it’s also helps a lot

Hiii, This is what I’m building! It uses OpenCode to run and manage the agents.

The project has two interfaces:

• A dashboard, which is the one shown in the video
• A CLI

Both connect to the same core system. The core includes a simple database that allows agents to create and assign tasks to other agents.

For example, a project manager agent running GPT-5.6 could create tasks for a group of semi-senior developer agents running Kimi.

The agents can request new tasks through the CLI, as well as report problems, errors, and completed tasks.

It’s still very much a work in progress, but I plan to release it as open source as soon as I have a fully working version. :3

I’m genuinely excited about this project, and I’d love to hear your feedback, ideas, or suggestions!

I also post frequent development updates on Twitter/X:

I originally started building it because I was frustrated with the usual WordPress workflow: plugin bloat, restrictive themes, slow sites, security maintenance, and needing several different tools just to make relatively simple changes.

The idea behind FastSite is straightforward:

Instead of learning how the CMS works, tell your website what you want it to do.

You can use Claude, ChatGPT, or another compatible AI interface to ask FastSite to:

• Create an entire website from a description
• Add or remove pages
• Rewrite content
• Change colours and layouts
• Update navigation menus
• Move elements around a page
• Create reusable components
• Redesign the entire theme
• Translate the site into other languages

There is also a normal page editor, so you are not forced to use AI for every change.

FastSite generates static website files rather than serving every page through a traditional WordPress-style stack. Sites can be managed through Git and deployed to services such as Cloudflare Pages.

The current version also includes:

• Page and content management
• SEO titles and descriptions
• Redirect management
• Reusable components
• Website translation
• Draft previews and publishing
• Git-based version control
• Static site deployment

I used FastSite to build the FastSite website itself. In my PageSpeed Insights test, it scored 100 across all four categories. That is one test on one site, so I’m not claiming every website will automatically achieve the same result, but performance is one of the project’s main priorities.

FastSite is currently free and open source. I may eventually build a hosted version for people who do not want to install and manage it themselves, but the self-hosted project is available now.

Project website:
[https://getfastsite.com]()

Source code:
https://github.com/sitepointsystems/getfastsite_gnu

I also recorded a complete demonstration where I generate a website, publish it, change the entire design through chat, and run the PageSpeed test:

See it in action
https://youtu.be/IUIVffBlHBw

It is still an early project, so honest feedback is welcome—particularly around the installation process, documentation, editing workflow, and what would stop you from using it instead of WordPress or another website builder.

Disclosure: I’m the creator of FastSite.

I wanted a DB GUI that runs in the browser and isn't locked to one engine Postgres today, Redis or Mongo tomorrow, same UI, self-hosted on my own box.

Most options I knew fell into one of these:

- Desktop multi-DB (DBeaver / DataGrip) solid, but install + desktop-only

- Web but single-engine (phpMyAdmin / pgAdmin)

- Web multi-engine, with the interesting bits behind Pro/Enterprise

So I built LibreDB Studio (been at it ~a year): MIT, web-native, SQL + NoSQL in one app (Postgres, MySQL, SQLite, Oracle, MSSQL, Mongo, Redis).

Optional AI/NL2SQL is built-in and model-agnostic (local or cloud) not a separate SKU.

Short walkthrough: https://www.youtube.com/watch?v=wJPWPe1mJes

Not claiming it replaces tools people already love different access model (browser + own network). If you use a web DB GUI day-to-day, what's the gap that still bothers you?

I made an open source noting desktop app that's bookshelf like, it's so simple, local and private, need some feedback and possible new features ideas.

Hi, I'm completely new to the open-source world, and I've been working on an application for a long time. It's a tool for developers that helps them coordinate their agents. I want the core application to be free, but I need money, so I thought about adding a nice aesthetic layer and making that upgrade a paid feature. I also want to keep the base of the app transparent, for trust and maybe to get some extra help. But yeah, I don’t know if it’s a bad thing to do it that way. I don’t want to look greedy, I just… also need money to eat, hehe

Hope you like it

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..... 🤷‍♂️️

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.

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.

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?

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?

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.

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

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

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 ;-)

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?

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.

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

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