A framework is a library, a platform is infrastructure

Agent frameworks give you abstractions for tools, planning and state inside your process. They do not route model traffic across providers, isolate code execution, persist sessions across restarts, enforce rate limits per tenant, or emit traces you can operate against. Those are the parts you end up building or buying separately.

Everstack runs alongside your framework, not instead of it

Point an existing agent framework at Everstack's OpenAI-compatible endpoint and it gains routing, fallback, caching, per-tenant limits and full request traces without a rewrite. Adopt the runtime later if you need durable sessions, sandboxed execution, approvals or evaluations.

When the framework alone is enough

For a single application, one provider, and no isolation or multi-tenancy requirement, a framework plus a hosted model API is less machinery and less to operate. The platform layer earns its place when several teams or tenants share the same AI infrastructure.
