Customer stories

What developers say about RouterBase

One API for every frontier model. Here's why teams ship on RouterBase.

Marcus Reyes
Marcus ReyesCTO, Paradigm AI

RouterBase cut our model ops from juggling 5 SDKs to one. We shipped twice as fast and our Q3 bill dropped 38%.

Priya Lakshmi
Priya LakshmiFounder, Quillo

We swapped three providers through RouterBase in one line of code when OpenAI had its outage. Our users never noticed.

Thomas Beck
Thomas BeckStaff Engineer, Northbeam

RouterBase's smart routing shaved 30% off our p95 latency — same prompts, better provider auto-picked per request.

Aoi Tanaka
Aoi TanakaML Lead, Daybreak Robotics

RouterBase's unified billing alone was worth it. No more chasing six platform invoices at quarter-end.

Jonas Keller
Jonas KellerIndie Developer

OpenAI SDK + a base URL swap = RouterBase. The whole integration took me less than writing this testimonial.

Ethan Nguyen
Ethan NguyenHead of Engineering, Compound Studio

RouterBase puts 200+ models behind one key. Our research team stopped asking for new provider accounts.

Sophia Martín
Sophia MartínCTO, Relay

RouterBase fallback from Claude to Gemini fires in under 200ms. For our chatbot SLA, it's non-negotiable.

Lucas Fernandes
Lucas FernandesEngineering Manager, Light

We migrated 42 services to RouterBase over a weekend. The only PR comment we got was 'wait, that's all?'.

David Okonkwo
David OkonkwoCo-founder, Figment

Through RouterBase we pay 20–30% less than hitting providers directly. The platform fee is transparent.
