Intercom alternatives compared

Chatwoot edges FreeScout 98 to 95, and most of the difference is stars: 39k stars against 4.6k stars.
The most recent release is Chatwoot v4.19.1, published 6 days ago. Zammad publishes no tagged releases, which costs up to 25 of the 100 points. None of the measured options scores under 40. By stack, Ruby (2) and PHP (1) are the most common. Tiledesk is permissively licensed; FreeScout and Zammad are copyleft. Chatwoot is source-available rather than open source, which limits commercial reuse.

How to choose a Intercom alternative
- Want the project most likely to keep shipping? Start with Chatwoot: health 98/100 and 475 commits in the last 90 days.
- Building it into a commercial product? Chatwoot is listed as proprietary; Tiledesk (MIT, health 70) lets you modify and ship it without publishing your changes.

- Planning to patch or extend it? Match your stack: Ruby (Chatwoot and Zammad), PHP (FreeScout).
- The score measures maintenance, not features: shortlist two and try them with your own data before you migrate.
