Maker
📌👋 I'm Jasmin Bhesaniya, the maker of BetterOpenSource.
Like a lot of you, I kept hitting the same wall: every tool I relied on — Figma, Notion, Slack, Analytics, auth providers — came with creeping subscriptions, per-seat pricing, and my data living on
someone else's servers. There are amazing open-source, self-hostable alternatives to almost all of them… but they're scattered across GitHub and genuinely hard to compare.
So I built BetterOpenSource — a curated directory of the best open-source alternatives to popular proprietary software. 🚀
What you can do:
- 🔍 Search any tool ("Figma alternatives", "Notion alternatives", "Clerk alternatives") and instantly see open-source options
- 📊 Compare tools side by side — features, license, GitHub activity, pros & cons
- 🗂️ Browse by category — design, productivity, dev tools, analytics, hosting, auth, AI, and more
- ⭐ Bookmark favourites, see what's trending, and read migration guides
- ⌘K command menu, dark mode, blazing-fast — and no signup required
A few favourites already in there: Penpot (Figma), AppFlowy (Notion), Mattermost(Slack), Better Auth (Clerk), Plausible (Google Analytics), and Aider/Cline (Claude Code).
Everything is free, and I review each tool against the same checklist — license clarity, project health, self-hostability, and what it actually replaces (cons included, not just hype).
My ask: What proprietary tool do you most want an open-source alternative to? Drop it below 👇 — and if I'm missing a great project, you can suggest it right on the site. I'll be here all day
Thanks for checking it out 🙏
