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 rather than guesswork. Its 60+ independent packages cover everything from a weekend project to a production SaaS, with no rewrite in between.
Stop prompting blind. With Talos, your work lives as structured specs that AI
agents can find, plan, and implement against your real conventions, with every
step transparent and verifiable.
What you get
Ship fast
Decorator-driven routes, services, and repositories with sensible defaults.
Go from idea to running app in minutes rather than days.
Built for the AI era
AI agents, RAG, and a Spec-Driven workflow live in the core, so 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 the
rest of the components every SaaS needs, ready to use.
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
Dependency injection and a clean module system let you add, swap, or
override anything without fighting the framework.
Spec-Driven Development at the core
Talos turns vague requests into structured specs: YAML issues with context, goals, a definition of done, and dependencies, all flowing through a transparent AI workflow.Find or Create
Audit your modules to surface issues and opportunities, or author a request
from scratch. Either way, the result is captured as specs.
