The web is better when your writing has a front door you control.
Self-hosted microblog CMS
Your domain.
Your voice.
A calm, portable home for short posts—without algorithms, walled gardens, or someone else’s rules.
Open source · AGPLv3 · Built for shared hosting
Small posts deserve a permanent home, too.
Why Bonumark Stream
Social posting,
without the social trap.
Social platforms are useful. They’re also rented space.
Rules change. Posts disappear into feeds. Audiences become locked inside systems you don’t control. Stream keeps the speed and ease of social posting, then puts the address, archive, and exit door back in your hands.
Publish like it’s yours
Short posts, long notes, photos, links, and standalone pages—all from the same clean publishing flow.
Build a real community
Profiles, accounts, comments, and likes bring conversation home without turning your site into a social network.
Leave whenever you want
Export your writing, make private backups, or publish a static copy. Your archive never becomes leverage against you.
Everything in. Everything out.
A publishing system
with an exit strategy.
Start with what you already have. Keep every reasonable way to take it somewhere else.
