Command Code
with your taste
The coding agent that does it all. Learns the way you code. Until coding feels like thinking.
Code 10× faster. Reviews, 2× quicker. Bugs 5× fewer.
Open models from $1/mo with $10-40 in free credits.
Trusted by devs at teams you trust.

the frontier coding agent
Casspr is the first frontier coding agent that both builds software and continuously learns your coding taste. Ships. Fixes. Tests. Refactors. Learns you, all the while.
//
stop patching AI slop.
//Slop. Generic. Not yours. LLMs generate sloppy code. Not your patterns. Not your taste. What if you could code like you think. Flow state accelerated with your coding taste.
//"Open models can't tool-call." They can. Your harness can't. Stop using open models with coding agents not built for them. Casspr closes the gap. Open beats closed.
Hello, taste. The meta neuro-symbolic AI model that pairs LLMs with your coding taste.
How does Casspr learn my coding taste?

Other coding agents. The same play.

Casspr. After it learns you.

Building cli, let me check your taste…
Using your taste, I see you prefer:
◻TypeScript for CLI
◻Commander and tsup
◻Vitest for tests
◻You prefer pnpm but do `npm link`
◻You like lowercased `-v` for cli version
Using taste, learning, building...
Done!
Built a date cli, with TypeScript, tsup, vitest
Also linked using `npm link`
Run `date-cli` to try it out.

“I'm a heavy $200/month Claude Code user and I can say that Casspr's handle on DeepSeek is really good. Every Claude user should try it out.”
“Casspr learns my taste. After a week, it stopped making the mistakes I kept fixing in other agents. The diffs feel like a senior engineer who already read the codebase.”

Questions, answered.
Everything that usually comes up before a team installs. Still curious? Read the docs, or join the Discord.
Casspr is a frontier coding agent that lives in your terminal and continuously learns your coding taste. Powered by taste-1, it ships, fixes, tests, and refactors with the patterns you keep — and forgets the ones you delete.
Every accept, reject, and edit is a signal. Casspr distills those into project-level /skills and personal /memory, so the next session opens with the conventions you already prefer. No rules to write, no prompts to maintain.
Every model listed in our docs ships out of the box — Anthropic, OpenAI, Google, xAI, DeepSeek, Qwen, Kimi, GLM, MiniMax, and more. New vendors land regularly.
No. Never. Your code, your skills, and your memory stay on your machine. Casspr never trains on your work. See the Privacy Policy.
npx taste push to publish a project skill, npx taste pull to install one. Skills are open files in your repo — review them in PRs like any other code.
Free tier for solo developers. Pro and Team plans add seats, more compute, and shared taste registries. See Pricing for the full breakdown.
