Overview

Tower is a self-hostable, Fly.io-style PaaS. Push your code and it boots as an isolated Firecracker microVM — with a dedicated database, vectors, and a multi-provider AI gateway wired up for you. It's invite-only and multi-tenant, so you can host friends, family, or a team on infrastructure you own.

What you get

• Git push-to-deploy — build a root Dockerfile straight from git push, with the build log streamed live.
• microVM isolation — every app runs its own kernel under Firecracker, safe for untrusted code.
• A database per app — dedicated Postgres + pgvector, injected as DATABASE_URL.
• One AI gateway — Anthropic, OpenAI, or Ollama behind a single endpoint; swap without redeploy.
• Invite-only multi-tenant — per-member isolation, on hardware you control.
