Elixir-native tooling for safer AI-assisted coding. Search and rewrite code by AST, detect duplication and generated-code slop, check architecture boundaries, and bootstrap strict mix ci quality gates — all with tools that understand Elixir syntax and BEAM projects.
mix igniter.install vibe_kit
mix ci
VibeKit is the quickest entry point: it wires Credo, Dialyzer, ExDNA, ExSlop, and Reach into new or existing Mix projects with one Igniter installer. The rest of the ecosystem is useful independently when you need deeper AST tooling, code-flow analysis, fixtures, or an experimental BEAM-native agent runtime.

└── vibe — experimental BEAM-native agent runtime
Agent-assisted Elixir development is safer when tools understand Elixir syntax, OTP runtime state, and project architecture instead of treating everything as plain text and shell output. Elixir Vibe packages keep analysis structured, outputs compact, checks cheap enough to run often, and BEAM-native workflows first-class.
