About

Customermates has an open-source CRM core for small teams, with contacts, organizations, deals, services, tasks and custom fields. It provides REST APIs, webhooks and authenticated MCP tools so compatible external AI clients and automation workflows can work with CRM records. The core can be self-hosted with Docker Compose under AGPL-3.0-only. Self-hosted installations use external AI clients through MCP. The managed cloud service also offers Mate, a cloud-only AI assistant, and a separately licensed unified inbox for supported email and social channels on eligible plans. The CRM core, hosted assistant and enterprise messaging have distinct licensing and availability conditions. Public source code and documentation explain the deployment options and supported integrations.

About

MergeMe mirrors GitHub pull requests and GitLab merge requests into Slack as a single, updating notification card per PR/MR. Unlike the official GitHub or GitLab Slack apps, which post a new message for every event, MergeMe edits one message in place as status changes (opened, in review, approved, merged). Review comments appear as thread replies under that card. Supported code hosts: GitHub, GitLab, and GitLab self-hosted. One workspace can connect multiple git sources at once. Route each repo or project to its own Slack channel, map GitHub/GitLab usernames to Slack users so @mentions actually ping reviewers, and use label-based routing to send bugs, features, and docs work to different channels. Setup takes about five minutes: connect Slack, connect your git provider (OAuth, GitHub App, or webhook URL for self-hosted), then add channel mappings. MergeMe uses webhook payloads only - it does not read your private source code. Free Hobby plan: 1 channel mapping, 5 users

Audience

Small businesses

Audience

Software development teams, engineering managers, and DevOps organizations that use Slack for daily communication and GitHub or GitLab for code review. Especially teams frustrated by noisy official Slack integrations, teams running GitLab self-hosted, and organizations that use both GitHub and GitLab and want one notification tool.

Pros & Cons from Real Users

Pros

  • Easy setup, intuitive workflow and n8n integration is great for automations. Very affordable in comparison to other CRMs

Cons

  • No phone support and some “advanced” stuff requires automations. No problem for me but maybe for other people.
