A lightweight code editor with Vim mode, Git integration, and more (athas.dev)

Athas Code Editor is a new, free and open‑source lightweight code editor that already ships syntax highlighting and Git integration and is actively developing Vim keybindings and Language Server Protocol support. The roadmap shows incremental releases: v0.1 (shipped: syntax highlighting, Git), v0.3 (Vim mode, in progress), v0.4 (language servers, in progress), v0.5 (agentic AI editing, planned) and eventual v1.0 with extensions. It runs on macOS, Linux, and Windows and targets developers who want a fast, opinionated but customizable editor without the bloat of heavier IDEs. For the AI/ML community the standout is built‑in, configurable AI support: users can plug in their own API keys and endpoints for OpenRouter, OpenAI, Anthropic, Grok, Gemini, etc., enabling experimentation with different LLMs and privacy/control over models. “Agentic AI editing” on the roadmap suggests future features for autonomous or multi‑step AI code transformations and assistant workflows inside the editor — useful for model-driven refactors, code generation, and prompting research. Being open source and extensible, Athas provides a lightweight platform for integrating LLMs, testing editor‑based agent workflows, and contributing improvements or extensions.
