Pros	Combines prompt, workflow, evaluation, and deployment in one platform Visual workflow builder lowers the barrier for cross-functional collaborators Solid evaluation and testing tooling for pre-production quality gates Multi-provider model support avoids lock-in Free tier lets teams trial without a credit card	Free, actively maintained open-source core with a large community Supports 100+ providers through one OpenAI-compatible interface Built-in cost tracking, budgets, and virtual keys Load balancing, retries, and fallbacks for reliability Can be fully self-hosted for data control
Cons	Pricing is opaque and sales-led, making budgeting hard Not open source, and self-hosting is locked to Enterprise Free tier is quite limited in credits, documents, and seats Smaller company and funding than infrastructure incumbents Frequent repositioning can mean shifting product focus	Self-hosting means you own deployment, scaling, and maintenance Advanced governance (SSO, RBAC, audit logs) requires the paid Enterprise tier Enterprise pricing is negotiated and not fully transparent Acting as a proxy adds an operational hop to debug when issues arise Feature breadth can make initial configuration complex
