afterburn·For AI startups
Pay for the model
your users need.
Compare hosted APIs and your own endpoints on your real prompts, route each feature to the cheapest one that stays fast enough, and keep a fallback ready for the day a provider goes down.
- Hosted and self-hosted together
- Fallbacks across providers
- Cost per feature
The work
Spend runway on product,
not on guesswork.
- Real prompts, real prices
Benchmark the providers you are weighing on the prompts your product sends, with the prices you actually pay.
- One route per feature
Chat, search and summaries can each have their own route, limit and fallbacks, all behind one key.
- Outages absorbed
When a provider fails, the gateway moves to the next endpoint on the route and logs the failure against the provider.
A month
Where the money
actually goes.
Cost per route and endpoint, from the gateway’s own logs.

Start with
one feature.
Give one feature a route, watch its cost, and move it when the numbers say so.
