Hi HN. I wanted an AI reviewer on every PR at work. Quotes came back around $1M/year, almost entirely per-seat licensing. I built a true open source alternative. We use it internally at Postman and the cost is ~$300/m in token usage.
It's open source, self hosted (also supports AWS lambda, cloudflare workers or Github actions) and can be deployed in under a minute.
It is lightweight (only diff is sent to the LLM), support any LLM provider and scalable. Our busiest repo has thousands of PRs a day and we usually get PR reviews within 30 seconds.
Give it a try and let me know what you think - https://nitpicker.dev
