esengine/DeepSeek-Reasonix
A reliable coding agent for complex software engineering tasks.
Reasonix is a coding agent that runs from a terminal, a desktop app, a browser, or an editor over ACP, with DeepSeek as the default preset and any OpenAI-compatible endpoint added through reasonix.toml. It is aimed at developers who want long autonomous edits on a model of their choice and need to read and undo what the agent did afterward.
The distribution story is concrete: CGO_ENABLED=0 gives a static single binary, and make cross builds six OS and architecture targets with nothing else to install on the target machine. The safety features are named and specific (plan mode, a permission gate, a workspace sandbox, and per-turn checkpoints with rewind), which is what makes an unattended run reviewable. Context handling is designed around prompt-cache stability, with a small stable startup summary, stale tool output pruned before summary compaction, and a documented tool schema contract for regression review. The 1.x to 2.x split is handled in the open: MIGRATING.md explains what the two lines share and how to run both without losing sessions, and the stable line has a stated maintenance policy.
The repo is carrying two products at once: a Go CLI, a Node and pnpm frontend that Studio needs to build (Go 1.25, Node 24, pnpm 10, and platform webview dependencies), a separate VS Code extension in another author's repo, and a 1.x npm line on main-v2. The VS Code extension currently requires the 1.x CLI, so editor integration targets the older architecture. 2.x is described as still moving quickly and is installable only from GitHub release archives, with no npm or Homebrew channel, so expect config and command churn if you adopt it now. The top-line claim that this is a reliable agent is asserted rather than measured in the README. There is a benchmarks directory, but the README gives no numbers, and the project's identity is tied closely to one named maintainer.
