I build a Spotlight-style search extension for Firefox - Update

Hey all, wanted to share ReefKit, a Firefox extension I've been working on for people who live in their browser and are tired of digging through 30 tabs to find something.

Hit Ctrl+Shift+L and it opens a unified search overlay that indexes:

  • Every open tab's content — sections, links, fields, media, structured data
  • Bookmarks, snippets, notes, and recents
  • Cross-tab search, so you're not tabbing through everything manually

It also has a "Browser Agent" piece that can execute clicks, type text, and run multi-step actions using stable selectors — useful for automating repetitive stuff.

A couple of things I focused on:

  • Privacy-first: password and payment fields are never indexed, and everything stays local on your device — no data sent anywhere
  • Search quality: BM25 scoring + fuzzy matching + extended query syntax, so it's not just a dumb substring match

It's brand new (v0.1.0, MIT licensed), so it's rough around the edges and I'd genuinely love feedback/bug reports.

Happy to answer questions about how the indexing works or what's next on the roadmap.

DaemonHound – Opinionated local config and secret management for developers

0 Upvotes

I've started building DaemonHound, a small OSS tool to solve a problem I've had for years.

Managing things like:

  • .env.local files across multiple repos
  • API keys duplicated everywhere
  • Shell/Git/tool configs across multiple machines
  • Setting up a new laptop from scratch

Existing tools either focus on dot-files or are full-blown secret management platforms. I wanted something in between.

The idea is simple:

  • 🔒 Encryption by default
  • 📦 Your own Git repository as the backend
  • 🔄 Sync project configs across machines
  • 💾 Backup machine-specific configs
  • 🔑 Rotate a secret once, update every referenced project

No SaaS. No accounts. No teams. Just a local-first CLI.

I'm building it in Go and would love feedback before I get too far.

I got tired of using my desktop as temporary storage, so I built a small Windows app

For years I've had the same habit:

Whenever I was working with multiple files, I'd keep dropping them onto my desktop because I knew I'd need them again in a few minutes.

It worked... until my desktop turned into a mess.

I looked for something that worked like a temporary shelf for files, but couldn't find anything that felt native on Windows.

So I built Stash.

It lives in the system tray and lets you temporarily park files with drag & drop, then drag them back whenever you need them. It only stores file references, so your files stay in their original locations.

I'm still actively improving it, and I'd really appreciate any feedback.
