Maige

Maige is open-source infrastructure for running natural-language workflows on a codebase, acting as an intelligent copilot that automates GitHub workflows. The site states it is used by more than 4,300 repositories and describes itself as best suited for large teams on its enterprise tier. It can automatically label and assign issues, add comments, review code, generate code, and run simple code snippets based on user-defined rules triggered by GitHub issues and pull requests, connected via webhook integration with codebase embeddings and sandbox environments. Maige is built by Rubric Labs as an open-source experiment. Pricing: a Standard plan at $30/month (first 30 issues free), a free trial with no credit card required, and an Enterprise tier listed as "coming soon."
