It's a Plan

Linear bills per seat; It's a Plan runs on your own server, where the seats are free and the AI agents take tickets too.

Antimatter

Mattermost started paywalling features it used to give away and sells the rest by the seat. Antimatter is the fork with the licence checks pulled out: SSO, LDAP, no nag screens, no invoice.

“Unfortunately, after a few disappointments at a previous company actually trying (and giving up) to buy a licence, and after their latest actions, which I could only call backstabs (paywalling previously available features, putting arbitrary limits that previously didn't exist, or recently adding nag screens to push people into either buying their licence or just away from their platform altogether), I've ended up fed up with their BS and started to work on a fork.”

Cairn Notes

Obsidian charges $5 a month to move your own Markdown between your own devices. Cairn syncs it through your own server and charges nothing.

“Obsidian made me pay them for syncing so I made an open-source implementation”

replacesSlack Pro · $8.75/user/mo

Deft

Slack bills you per head, per month, forever. Deft puts chat, tasks and notes on your own server and bills you nothing.

“This started with three things: wanting Slack to do more, a growing resentment of SaaS bills, and getting slightly too obsessed with self-hosting.”
