We integrate open-source software for you to pay less in long-term and own your data.


We believe that p2p services based on open-source is better, than unfair-priced SaaS products within shared economy.

Imagine your Uber taxi stops, catches another person, makes a detour and only then finishes the ride. Or AirBnB decides that a stranger will live in the place you're renting, because it's "optimal".

Digital SaaS companies make this every single day.

Stage: idea, 2 showcases


SaaS 0x0
Plan hard-coded options, sometimes you pay "per human" even if they're inactive you decide: market-driven for services, sufficient for hardware resources
Roadmap they decide you decide and free to fork
Dedicated features expensive enterprise plan, still no promises bid for your wish on a free market
Billing separate different bills and cycles single check
What your paying for all features (including not needed future), rent hardware (for that "free-plan" guy as well), all staff (including theirs marketing team) your hardware (buy or rent), market-driven for price additional (custom) services


  • install with a single command (on-premise too!)
  • transfer your data (import archives exported thanks to gdpr)
  • get updates guidelines and support

If my team won't like it, can I migrate back to GitHub/Trello/Slack?

Yes, we are aginst any vendor-lock (if target-saas is welcoming digital nomads)

Can I migrate back to another free open-source solution?

Yes, because you own your data and free to move it anywhere else, anytime.

Should I run a server/vps?

Yes, but we're thinking towards a federated solution w/o a central server.

Motivation parallel

Saas Oss
Inheritance No Fork
Incapsulation API Protocol
Polymorphism ? Standards, RFC


  • selfhosted opensource groupware doesn't have to scale to millions requsts-per-second, it just needs to work
  • under big timepressure you don't strictly need to follow some api, you can manipulate the database directly: this can ease introducing various integrations (no need to wait properly upstream-approved api extension) ofc, as any boundary violation this has its drawbacks, however with a 3rd-party SaaS you NEVER can do that
