As answered by people managing Helicone AI and PullPro.dev.
PullPro.dev's answer:
Engineering managers and tech leads at teams of roughly 10–200 developers who use GitHub and Slack and want reviews to stop stalling.
PullPro.dev's answer:
TypeScript on Cloudflare Workers, Postgres, the GitHub and Slack APIs, and Next.js.
PullPro.dev's answer:
It waits for a pull request's required checks to pass before posting it to Slack, so reviewers only see PRs that are actually ready. From there reviewers claim a PR with one click, the message updates in place as the PR moves, and a weekly report shows how long reviews take. It's priced per channel, not per developer.
PullPro.dev's answer:
Most PR-to-Slack tools charge per seat, so the bill grows every time you hire. PullPro is priced per channel with unlimited developers on every plan, including free. It's also built around review flow rather than notification volume: one message per PR, clear ownership through claiming, and reminders that stop once someone picks it up. The official GitHub app, by contrast, posts every event.
PullPro.dev's answer:
I built it for my own team at work. Pull requests kept getting lost in noisy Slack channels and reviews sat for days. We've used it for a few years, and I recently opened it up so other teams can use it too.
