Interesting talk this week with
@piotrkulpinski , the founder of
@ossalternative, a community-driven directory of open source alternatives to SaaS tools.
OpenAlternative traction tells a story:
- 100,000 unique visitors in its first week
- #1 on Hacker News
- Crossed 1M unique visitors in 2025
That's a forward-looking signal.
Self-hosted open source is having its moment.
A few names you'll find on the site:
🤖
@n8n_io : AI-powered automation toolset.
🔍
@meilisearch : fast search engine for websites and apps
🌐
@hoppscotch_io : lightweight API client for testing endpoints on the fly
🤝
@twentycrm: open source CRM for contacts, deals, and collaboration
🛍️
@spreecommerce: headless eCommerce with REST API, TypeScript SDK, and Next.js storefront (integrated with Meilisearch, by the way)
Why does this matter?
Piotr said it better than I can, so I'll paraphrase him in three beats:
1️⃣ Transparency - it's open to humans and agents
2️⃣ Community - a pool of developers using and contributing
3️⃣ Freedom
👉 no vendor lock-in
👉 no dependence on one company's roadmap,
👉 full control over your own infrastructure and data
That last one lands hardest for anyone who's ever been deplatformed, repriced, or regulated.
Spree Commerce is built for exactly this moment.
Open source and free to self-host anywhere.
- Headless by default with a full REST API and OpenAPI 3.0 spec.
- TypeScript SDK and a Next.js storefront ready to fork.
- Bundled documentation in every Spree Commerce install.
- AGENTS.md file maintained by the Spree Commerce team.
Here's the quiet revolution part.
AI coding agents love open source.
Why?
- They can read every line of source code.
- Full documentation is local and indexable.
- No API gates, no paywalls, no rate limits on what they can learn.
- Years of community tutorials, GitHub issues, and public forums already live in their training.
On a proprietary SaaS platform, the agent reasons from the outside in: outdated docs, blog posts, marketing pages, and whatever scraps the public API exposes.
With Spree Commerce, the agent reads the codebase.
Different level playing field.
Whether you're building:
- a B2B wholesale portal,
- a multi-vendor marketplace,
- a multi-tenant SaaS dealer network,
- or a regulated commerce operation where the data has to stay yours
...self-hosted open source is no longer the compromise option.
It's the strategic one.
Open source is the new stack. Again.
Try Spree Commerce for free.
