The pain point is real: developers juggling multiple LLM APIs face cost unpredictability, latency variance, and provider lock-in. The gap is a single control plane for routing, caching, and observability. Hard part is distribution — selling to developers requires deep technical credibility and community trust. What has to be true: you can get 100 active developers to try it via open-source or a free tier, and they see immediate cost savings or latency improvements.

The idea

The pain point is real: developers juggling multiple LLM APIs face cost unpredictability, latency variance, and provider lock-in. The gap is a single control plane for routing, caching, and observability. Hard part is distribution — selling to developers requires deep technical credibility and community trust. What has to be true: you can get 100 active developers to try it via open-source or a free tier, and they see immediate cost savings or latency improvements.

LLM API costs are unpredictable and growing fast. Developers want to avoid vendor lock-in but lack tools. Latency optimization is a key differentiator for real-time apps.

Growing LLM market needs infrastructure Cost/latency pain is real but not critical

Why now

Heuristic scoring based on model judgment, not factual measurement.

LLM APIs mature, need orchestration AI-first companies are standardizing Portkey leads but niche for routing

The market is growing rapidly (Portkey's $15M raise, 24K+ organizations) but incumbents are enterprise-heavy. There is a window for a simpler, cheaper alternative targeting indie developers and small teams. Timing is favorable for a lightweight MVP that emphasizes cost savings and ease of use.
