The self-hosted promise is fulfilled — Recuerd0’s source code is on GitHub.
When we announced Recuerd0, we said the self-hosted version would be available pretty soon. Today it is. The full source code is on GitHub under the OSASSY license.
This is not a stripped-down edition. It’s the same codebase that runs recuerd0.ai — every feature, every endpoint, every migration.
Under the hood
Recuerd0 is a Rails 8.1 application running on Ruby 4.0. The entire stack leans into the One Person Framework philosophy: minimize infrastructure, eliminate external dependencies, ship with confidence.
SQLite for everything. Data, cache, queue, and cable — all backed by SQLite. No Postgres. No Redis. Solid Queue handles background jobs, Solid Cache handles caching, and Solid Cable handles WebSocket connections. One database engine, zero extra services.
No Node.js. The frontend uses Propshaft for asset delivery and Importmaps for JavaScript modules. Hotwire (Turbo + Stimulus) handles interactivity. Tailwind CSS 4 handles styling. The entire frontend pipeline runs without a JS build step.
Full-text search with FTS5. Search is powered by SQLite’s FTS5 extension — no vector database, no embeddings, no RAG pipeline. The index updates on every write, returns results in milliseconds, and is fully deterministic. The agent decides what to search for; the database does the rest.
Memory versioning. Every memory supports a flat branching model — create new versions from any point in history. Soft deletion with 30-day retention means nothing disappears by accident.
Multi-tenancy. The Account model supports multiple tenants. In single-tenant mode (the default for self-hosted), public registration is disabled — you control who has access.
UI components. The interface is built with the maquina-components gem, the same component library used across all Maquina projects.
Getting started
Two paths to self-host:
Docker image. Pull the ready-to-use Docker image and deploy. Configure your environment variables and you’re running.
From source. Clone the repository, configure Kamal 2.x, and deploy to your server. The included Dockerfile and Kamal configuration handle the rest. Thruster sits in front of Puma, and SOLID_QUEUE_IN_PUMA=true runs background jobs in-process — one container, one process, everything included.
Single-tenant mode is the default. No public registration, no setup wizard. Deploy, create your account, start curating context.
License
Recuerd0 is released under the OSASSY license. It’s essentially MIT with one restriction: you can’t take the code and offer it as a competing hosted service. The same model 37signals uses. Deploy it on your infrastructure, modify it, use it internally — free forever.
Not interested in self-hosting?
Recuerd0 SaaS is $15/month for up to 10 users — managed hosting, automatic backups, and updates. Read the full product announcement for the complete story.
