Talos is a modular TypeScript framework built on Bun. It’s the first framework designed around Spec-Driven Development, so AI agents work from your real intent, not guesswork. 60+ independent, batteries-included packages take you from a weekend project to a production SaaS without rewrites.
Stop prompting blind. With Talos, your work lives as structured specs that AI
agents can find, plan, and implement against your real conventions — every
step transparent and verifiable.
Why Talos
Ship fast
Decorator-driven routes, services, and repositories with sensible defaults.
Go from idea to running app in minutes — not days.
Built for the AI era
First-class AI agents, RAG, and a Spec-Driven workflow baked into the core.
Your framework speaks the language of the tools building it.
Scales with you
The same framework powers small side projects, medium products, and large
multi-service platforms. Start simple, grow without rewrites.
Build your SaaS faster
Auth, JWT, roles, permissions, payments, caching, queues, mailer, and more —
the components every SaaS needs, ready out of the box.
Everything you need
60+ independent packages spanning HTTP, data, security, real-time, AI, and
utilities. Use only what you need; each is versioned on its own.
Easy to extend
Built on dependency injection and a clean module system. Add, swap, or
override anything without fighting the framework.
The first Spec-Driven Development framework
Talos turns vague requests into structured specs — YAML issues with context, goals, a definition of done, and dependencies — that flow through a transparent AI workflow.Learn Spec-Driven Development
