Hey, I am Massi.

Solo developer based in Rome. I work on open source full time, mostly the kind of tools I wished existed.

The two projects I am putting most of my time into right now:

webclaw is a Rust web scraper for AI agents. No headless browser, just raw HTTP with a proper Chrome TLS fingerprint. Fast, does not get blocked on most sites, and sends 67% fewer tokens than raw HTML to your LLM. AGPL.

Stik is a fast, local-first thought capture app for iOS and macOS. Type something, it stays out of your way. No accounts, no cloud sync unless you want it.

I also keep a few smaller things alive: a Reddit pain-point finder (redditlens), a couple of Claude Code skills, and the boring infra that keeps it all running.

Why sponsor

The way I keep shipping fast is by having no meetings, no roadmap committee, and no one to please except the people who actually use the tools. Your sponsorship pays for the part nobody else pays for. Bug fixes nobody asked for. Cleaner docs. The slow weeks where I rewrite something that bothered me.

If you use webclaw to build your AI agent, or Stik to keep your thoughts in one place, this is the most direct way to support the work and keep it open.

What you get

The tiers below give you progressively more skin in the game. The $2 tier is a thank you. The higher tiers come with a real say in what I build next. Pick whatever feels right.
