Operate
You ship the product. We run the models.
Every model runs on several upstream channels: weighted routing, automatic failover, smart retries and continuous health checks — when one line fails, your users never notice.

One key opens every frontier model
Chat, coding, reasoning, image and video generation — with public, transparent prices.
Every modality
Beyond text
Text, image, audio, video and embeddings with a single key.

Collaborate
One account. Your whole team.
Give every project and teammate its own key and budget, so cost and risk stay visible.
Team keys
Manage keys like you manage people
Separate keys — One per project or teammate, fully isolated.
Quotas & budgets — Set a cap; spending stops when it is reached.
Model allowlists — Restrict which models each key can call.
IP restrictions — Only trusted sources get through.
Workflow
From first call to monthly close, in one place
Request logs
Model, tokens, latency and cost are recorded for every request.
Dashboards
Track spend over time and by model.
Easy top-ups
Top up online or with redemption codes; balance is usable right away.
Secure sign-in
Passkeys and two-factor authentication.
Insight
See everything. Waste nothing.
Every call leaves a trail: logs, dashboards, per-token pricing and budget guardrails keep cost under your control.
Request logs
Every call, fully traceable
Usage analytics
Trends by day and by model
Cost breakdown
Input, output and cache priced separately
Budget guardrails
Inside the cap, never a surprise bill
Community
Growing with developers
Real feedback from individual developers and teams.
I pointed Claude Code's base URL at FlyMux and haven't touched it since. Rate-limit pain is basically gone, and the bill is clearer than before.
We A/B four or five model vendors at once. It used to mean a key and an invoice per vendor — now it is one console and one monthly close.
The failover sold me. An upstream went down, users felt nothing, and I only found out the next day reading the logs.
Every project gets its own key with a budget, and that's it. No intern can burn the team's whole balance overnight anymore.
OpenAI SDK and Anthropic SDK both speak their native protocols — no weird compatibility layer. Migration cost was basically zero.
Per-token billing is genuinely itemized: input, output and cache counted separately. Cache pricing alone cut our monthly spend by nearly 30%.
Long-running agents fear a flaky model layer most. With FlyMux the retries and switching happen at the gateway — I removed every fallback hack from my code.
New models usually show up on the models page the day they launch. Prices are right there — trying one is just changing the model name.
