I forked Chromium to fix my browser automation headaches with Claude Code.
It's called Shuttle: every agent gets its own identity, its own logins and its own tab group. The MCP server is built in.
Free and open source:

Introducing Vitals CLI
The Activity Monitor alternative that thinks in apps, not processes. Now as a command.
> brew install --cask foredotstudio/tap/vitals

I forked Chromium with Claude Code so my agents can use a real browser.
It's called Shuttle: every agent gets its own identity, its own logins and its own tab group in your window. The MCP server is built in.
Free and open source (BSD-3).
Small MCP surface: 12 browser tools + 24 page tools, powered by @vercel agent-browser (bundled).
Per-session CDP endpoints for Playwright, for scripted e2e tests.
Removed from Chromium: Google sign-in, sync, telemetry, Google AI, translate, password manager and more.
Free and open source (BSD-3). Built mostly with Claude Opus 5.5. I'd love your feedback and ideas.

No matter how good AI gets at copywriting, design, or video… Handing it to someone with no directing skill is like giving a junior a team of world-class talent and zero brief. They’ll just produce tons of mediocre results faster.
1/ Image models cannot emit an alpha channel. Ask one for a transparent background and it paints the Photoshop checkerboard straight into the RGB pixels. Here is that answer sliding across a coloured surface, fake checkerboard and all.
6/ Turns out what separates a lattice from radial art is position, not contrast. Measuring transition concentration per axis: synthetic checkerboards 1.000, real radial art 0.211 to 0.313. The roses now pass first try, cutting three API calls to one.
7/ Two model calls per asset instead of one, three when the guard re-rolls. Worth it: a chewed edge cannot be repaired afterwards.
CLI, library and Claude Code plugin, MIT: github.com/tobiasstrebitzer/…
What else are we asking models to do that they cannot?
1/ I can now bring real Claude Code sessions into my products. In the video: my GTM dashboard on the right kicks off tasks, a hosted Claude Worker on the left runs them. Github repo (MIT): github.com/tobiasstrebitzer/…
7/ Claude Worker also allows for setting up multiple profiles, so each user can have their own settings, memory and tool access. This was a strong requirement for my team operating agents across varying business functions.
