Choose Rocket.Chat.
If you want to own your data, save money, and avoid vendor lock-in, Rocket.Chat is open source and community-driven.
What Actually Matters
No fluff — just the differences that affect your decision
Rocket.Chat is open source (Other). Slack isn't. You can fork it, audit it, host it yourself — no permission needed. That matters.
Rocket.Chat lets you self-host with Docker — your data, your rules. Slack? Cloud only. If privacy matters, that's a dealbreaker.
Rocket.Chat dominates with 46.3k GitHub stars vs 0. Bigger community = more plugins, more answers on Stack Overflow, faster bug fixes.
Rocket.Chat is built in TypeScript — you can read the source, contribute, or fork it. Slack is closed-source, so you're trusting their engineering.
Try both — most offer free tiers. The right pick depends on your stack size, team, and tolerance for DevOps.
