- Browser UseOpen-source framework for LLM-driven browser agents
You need browser infrastructure—Browser Use is a framework, not a managed service. Token consumption scales with page complexity. Anti-bot measures will block you without stealth tooling.
- LangfuseOpen-source LLM observability you can self-host
Self-hosting means self-operating—you are running Postgres, ClickHouse, Redis, and the app. Observability-first means evals are layered on, not central.
- LiteLLMMIT OpenAI-compatible gateway to 100+ LLMs; Enterprise SSO paid
Vs OpenRouter/provider SDKs: self-host gateway you operate — not a hosted model marketplace. LOUD: enterprise/ tree and SSO/audit/RBAC are commercial; core proxy stays MIT. You still pay model providers.
- InstructorMIT Pydantic structured outputs for any LLM; free library
Library not an agent framework (pair with your orchestrator). Provider token costs remain. Vs native structured-output APIs: Instructor shines on validation/retry DX across providers, not on replacing tool-calling agents.
