Axolo requires full api access to your GitLab — that's admin-level write access. PRFlow only needs read_api. Read-only, always.
Works with gitlab.com and self-hosted GitLab.
Axolo requires full api scope access to your GitLab. That's write access — it can modify repositories, merge requests, and project settings on your behalf. PRFlow only asks for read_api scope. It reads MR metadata and comments, and that's it. No write access to your GitLab, ever.
Axolo's core model is one Slack channel per merge request. Every MR gets its own temporary channel — that's the experience it's built around. PRFlow works in your existing channels — one updating message per MR, with review comments synced to a Slack thread.
Built exclusively for GitLab. Axolo splits focus across GitHub and GitLab. PRFlow goes deep on one platform — every feature is designed around GitLab's merge request model, CI/CD pipelines, and webhook events.
An honest, side-by-side look at what each tool offers for GitLab teams.

Both tools deliver GitLab MR notifications to Slack. PRFlow's edge: GitLab-only focus and a simpler notification model.
A single Slack message per merge request that updates in place as the MR progresses. Pipeline status, approvals, and merge all appear on the original message.
Every feature is built around GitLab's merge request model, CI/CD pipelines, and webhook events. No compromises for multi-platform support.
GitLab review comments appear as Slack thread replies on the MR message. The discussion stays organized and your channel stays clean.
One approach: messages in your existing channels. No notification modes to choose between, no channel-per-MR cleanup. Connect GitLab, pick a Slack channel, done.
