Code review that usesyour own AI agent.
GitGecko can run through a supported local coding agent after that agent is configured and authenticated. Local reviews do not require a GitGecko cloud account.

What GitGecko adds to the workflow
Three structural advantages — not marketing claims
Use your existing agent
Run through a supported local coding agent after its own setup is complete. GitGecko adds deterministic analysis and review structure without requiring a cloud account.
Existing-agent execution
Deterministic-first
ast-grep + regex rules run before the LLM. Deterministic findings are reproducible and do not depend on model quality; model findings remain probabilistic and are shown with provenance.
Deterministic signal before model output
Self-host or cloud
The local and hosted products share one codebase. Hosted plans remain private preview until billing and entitlement verification is complete.
One local and hosted product path
Illustrative output shape
See the result before you connect a repository
A review is not a paragraph hidden in a comment. It is a navigable artifact with a verdict, impact signal, exact location, evidence, and traceable source.

Run a local review with your existing agent
Install and authenticate a supported agent first, then let GitGecko detect the available pathway
Install the CLI
Run npx gitgecko review in any repository after configuring Claude, Codex, OpenCode, or a supported model provider.
GitGecko detects your agent
claude, codex, or opencode can be invoked through the detected local pathway. The agent's own authentication remains its responsibility.
Get structured findings
Deterministic rules run first (ast-grep + regex), then the LLM. Severity-tagged, trace-backed, zero hallucination on the deterministic lane.
