ForgeRelay

Compare Named comparison

One living thread instead of a GitHub event firehose.

GitHub’s official Slack app is free, official, and good at slash commands and Copilot in Slack. ForgeRelay is for teams that want one conversation per pull request — and GitLab or Discord in the same product.

Stay with GitHub Slack

The official app is the better fit when…

  • The team only uses GitHub, and Slack is the only chat that matters
  • Slash commands and Copilot-in-Slack are part of the daily workflow
  • A free official GitHub integration is more important than a quiet thread
  • Issue, commit, and deployment pings as separate channel messages are acceptable

Switch to a relay

ForgeRelay earns its place when…

  • Each pull request should own one living Slack or Discord thread
  • Review requests should mention a mapped person, not a GitHub handle
  • GitLab merge requests need the same treatment as GitHub pull requests
  • Pipeline failure and recovery should land in that same thread
  • A missed delivery has to be explainable and replayable

FAQ

Questions worth answering before you switch tools.

Yes. Unsubscribe noisy GitHub Slack subscriptions for repositories you route through ForgeRelay, and keep the official app for commands or other events.

No. GitHub and GitLab are both sources. Slack and Discord are both destinations.

ForgeRelay vs GitLab Slack app

GitLab’s official Slack app covers a wide event catalogue, slash commands, and GitLab Duo in Slack. ForgeRelay is for teams that want one conversation per merge request — including pipeline recovery — and GitHub or Discord in the same product.

ForgeRelay vs Axolo

Axolo creates an ephemeral Slack channel for each pull request and lets the team review bi-directionally from Slack, including /lgtm. ForgeRelay leaves approvals in GitHub or GitLab and posts a quiet living thread instead.

Read comparison

ForgeRelay vs PRFlow

PRFlow keeps a live Slack card that shows what is left to merge, and it publicly markets GitHub plus GitLab including self-hosted GitLab. ForgeRelay is the closer fit when Discord, commit digests, delivery replay, or per-route overrides matter.
