Local-first C tools. No frameworks. No telemetry. No package manager.

—— I ——
One agent, one editor, one engine, one browser workspace — each in a single file of C (or HTML), each building with nothing but a compiler. Versions and release notes live with each repo; the site lists them all.

hako-edit · hake · modal terminal editorSingle-file C99, vim-flavored. Splits, a file explorer, a runner pane for the compile/fix loop, the suite's themes, mouse, UTF-8 — and the hako agent in a pane beside your code.
|
| — II — |
hako-code · hako · standalone agentA coding agent in one C file. Local hako models by default, or the cloud provider you choose — Anthropic, Copilot, GitHub Models, OpenRouter, Gemini and the OpenAI-compatible rest. Tools behind approval, sessions, Agent Skills, MCP, self-update. Runs where nothing else installs — one binary, libc and a shell, so it works on a phone under iSh, editing real files. |
| — III — |
hako · hakm · native C engine + model familyFrom-scratch inference: own loader, k-quant + int8 kernels, BPE. No llama.cpp, no ollama. Runs the hako models, on 🤗 huggingface.co/mithraeum: hako-sho — 3B · hako-koi — 7B · larger fine-tunes to follow.
|
| — IV — |
hako-studio · the agent in a browser · hako.mithraeum.studio The same hako.c, compiled to WebAssembly — so the agent runs on your own device, in a tab. Open it hosted with nothing installed, run the container, or serve it from the binary with hako --serve. No backend, no database, no account; your key goes straight to the provider and your work stays on your machine.

skills · behaviors Markdown skills in the open Agent Skills format, for the whole suite and any agent that reads them. Drop a folder, name it, the agent loads it. No runtime. |

- C99 / C17. libc + pthread.
curlas a subprocess where needed. That's the stack. - Single-file where reasonable. No premature splitting.
- Tests that need nothing. Every repo has a
make testwith no model, no network and no credentials; ASan is a ship gate. - No telemetry. No analytics. No daemon. The binary does the thing and exits.
- Releases over package managers. Release binaries with sha256 sidecars, a source build
where there is none, and
--updatedoes the rest. - Local-first models. Run on your device. Offline. Forever.
