For investors
A backend small enough for agents.
One small program: data, sign-in, and access rules. For SaaS apps and .
Why it is different
The usual backend is a pile of services — database, login, search, files. We measured that at twelve processes and about 1.85 GB of RAM sitting idle.
Librebase does the same job as one process. About 2 MB idle. Agents and tenants fit on a machine that used to hold one project.
Why agents, and why SaaS
Agents open many short sessions, search by meaning, and keep going without a person watching. A heavy stack makes that expensive and brittle. A small one with sign-in and row rules already on does not.
A small SaaS product often pays three vendors before the first user — often €60+ / month. Starter is €9 for the same job. Self-host is free on your hardware.
Against the usual options
| Librebase | Usual stack | Database-only | |
|---|---|---|---|
| What you run | One program | ~12 services | Just the database |
| Idle RAM | ~2 MB | ~1.85 GB | You add the rest |
| Sign-in + rules | Included | Extra services | You add them |
| Pick it when | Agents, density, one bill | You need every feature today | You only need SQL |

Core paths are faster. Files too. We are not a full Supabase clone — storage and extra Postgres features come next. Numbers · Glossary
