Most communities online live on borrowed land: a platform that owns your members, sets the rules, raises the price, and can lock the doors whenever it likes. Mosaic is the opposite. We co-design a space around how your community works, and you own it outright: forkable, exportable, impossible to take away.
◼ We work closely with a handful of communities a year. We build the space with you and hand it over as yours.
Rented vs. owned
There are only two ways to run a community space. The difference comes down to who holds the keys. See how the options stack up →
What "yours" actually means
We start from how you already gather (your roles, rituals and rules) and build the space to match. It looks and works like nowhere else, because it's made for one community: yours.
Open source and yours to keep. Forkable, exportable, no per-seat trap, and no subscription you're locked into. Take it to another team or run it yourself whenever you decide.
The public face and the conversation on the same system, in the same identity. Members move between them without noticing a seam.
Federated with the wider open social web, so your members can reach the world, but only as much as you choose. Open the doors wide, or keep it private and invite-only.
How we build it with you
Mosaic is those two things in a room together. You make the calls about how your community should run; we work out what that means in software, and everything we build goes back into the commons.
Interviews and workshops with your people. How do you gather? Who decides what? Where does it break down today? We've never yet found a community that works the way its org chart says.
Together we shape the space: the circles, the roles, the boundaries, the flows. You make the calls about how your community should run; we work out what that means in software.
When possible this is simply assembling building blocks that already exist, and that doesn't stop at Bonfire's own extensions. Rather than succumb to "not invented here" syndrome, we interconnect with dedicated open-source tools across the wider ecosystem. We only write new code where something doesn't exist yet, and when we do, it becomes a block anyone can reuse.
Your brand, your language, your governance, and training for the people who'll actually run it day to day: your facilitators and your moderators. It's yours from here.
We get you set up on our cooperative hosting network, or help your team with installing it up on your own infrastructure. And we remain available for updates, fixes and new features.
Who we've built with
The same foundation, shaped three ways: a magazine, a research network and a care coalition need almost nothing in common. Each one owns what we built together.

A community of readers who debate and belong. Publishing stayed on their Ghost site; the community lives on Bonfire, wearing their brand.

Co-designed with working researchers: ORCID sign-in, publications on your profile, papers that unfold with their DOI.

Private, invite-only, carefully moderated. Safety and governance designed in from the first workshop.
The part no agency can offer
Everything built in Mosaic is open source and goes back into the commons. That changes the economics. Your budget builds shared building blocks that every community draws on, and your own space grows out of it.
Ways to work together
Every route is bespoke. We don't do per-seat plans or off-the-shelf tiers. Where you land depends on how much your community needs shaped.
Bonfire wearing your identity, with your governance and the integrations you already rely on.
Your community needs capabilities nobody's built yet, the way researchers needed DOIs on their profiles.
The unglamorous part that keeps a space alive: we maintain the code, a co-op runs the infrastructure.
Tell us your budget and we'll tell you honestly what's possible, including when the answer is "you don't need us, here's how to do it yourself." And if self-hosting is the right call, we can still help you get there through community install parties or a 1-on-1 setup session. We'd rather send you away with a working plan than take money for a project that shouldn't happen.
Let's talk
We take on only a handful of communities a year, and we start by listening. If it's a fit, you walk away owning something no one can take from you.
