This is the most opinionated FastAPI starter we've seen—it gives you auth, payments, AI, and a control plane out of the box while letting you add or remove components later. The trade-off is that you deploy and maintain it yourself; there's no managed cloud option. Strong buy for Python SaaS teams that want to move fast without rewriting later.

How we score →Aegis Stack scaffolds complete FastAPI applications with built-in auth, payments, workers, AI agents, and a control plane. It is designed for teams and solo developers who want to ship production-grade Python backends quickly without sacrificing maintainability. The framework uses a modular component system: core pieces (backend, CLI, frontend) are always included, while optional infrastructure like Postgres, Redis, Ollama, Traefik, Logfire, and task queues can be added or removed via CLI flags. Each component arrives pre-configured and wired to the rest of the stack. Services are the product layer—auth with session rotation and RBAC, markdown blog publishing, AI conversational agents with RAG across eight providers, and billing integration. They ship as working code in your repository and can be enabled per project. The stack updates when the framework improves, reducing technical debt. It powers Aegis Pulse, a real-world metrics product tracking GitHub traffic, PyPI downloads, and docs visits. Aegis Stack is open source, Python 3.11+, and available via uvx.
Aegis Stack lands in the sweet spot between a bare framework and a managed platform. It gives you production scaffolding—auth with RBAC, Stripe billing, AI agents with RAG, background workers, and a live dashboard—without locking you into a proprietary runtime. The modular component system is its killer feature: you can add Postgres, Redis, Ollama, or Traefik via CLI flags, and remove them just as easily. The `aegis update` command pulls in template improvements as diffs, so your codebase stays current without manual merge hell. Where it bites: you own the deployment. There's no Aegis Cloud—you SSH into a VPS, run `deploy-setup`, and manage Docker/SSL yourself. If you want a fully managed backend-as-a-service, look elsewhere. Also, it's FastAPI-specific; Django or Express devs get nothing. Compared to alternatives like Django CookieCutter or FastAPI best-practices templates, Aegis is more opinionated and ships more working code (payments, AI, observability). But it's heavier—if you just need a CRUD API, a simpler starter will do. In practice, we'd reach for this when building a SaaS MVP that needs auth, billing, and AI conversations day one. The built-in Overseer dashboard and CLI telemetry mean you get observability without extra setup. Just be ready to handle the ops side yourself.
