The platform

Everything, in one place.

Each project gets the full set the moment it's created. No wiring, no glue code, no surprise invoices.

PostgreSQL Database

Dedicated database per project with pgvector, full-text search, and all extensions included.

Object Storage

S3-compatible storage for files and media. Mounts as a drive on your Mac.

Compute & Deploys

Push to git and ship containers — Node, Python, Go, Rust, static sites and more.

Custom Domains

Bring your own domain via CNAME or A record, with automatic SSL on every hostname.

Auto-Pause

Idle projects pause automatically. No charges for what you're not using.

One Dashboard

All projects, usage, and billing in one place. One invoice, ever.

Agent-native

Your AI already knows its way around.

Mosaic ships a skill your coding agents install once. From then on they create projects, provision databases, push code and read logs — programmatically, no hand-holding. Full documentation for humans and agents at /docs.
