A 5 MB daemon that streams every agent event to your client — text deltas, tool calls, thinking steps, all of it. Connect what you need, skip what you don't. One curl to install. Bring your own model.
I write systems software. I looked at OpenClaw — 1.2 GB. Hermes — 40+ bundled tools. Why does your agent ship someone else's choices?
CrabTalk is a daemon. 8 MB. You put what you need on your PATH — your search, your gateway, your tools. They connect as components. They crash alone. They swap without restarts.
You could build any of those apps on top of CrabTalk. You can't build a CrabTalk underneath them.
The Unix philosophy applied to AI agents. Most frameworks today bundle everything and ship a bigger binary. But if you've run agents in production, you know the bloat is where the bugs hide.
8MB with native Rust and no GC is the kind of foundation you want for agents running continuously. "Components crash alone and swap without restarts" is how real infrastructure works. Refreshing to see that mindset in AI tooling.
As someone who builds native Mac apps and cares about binary size and resource usage, I appreciate tools that respect the machine. Curious about memory profile under sustained load with multiple agents running at once.
Been nipping at your heels all day. Congrats on the launch, amazing product!
streaming thinking steps alongside tool calls in one feed is what almost nothing does by default. curious what happens with concurrent tool calls - does the stream stay coherent? also 8MB is impressive, what's the runtime?
