Stop rewarding API abuse
Policy-driven rate limiting for fair API usage
Fairvisor helps you control API growth, protect your infrastructure budget, and enforce fair usage across all clients.
Problem → Solution
Fairvisor turns chaos into control
Before
Chaos, manual scripts, DDoS, unfair usage
- Reactive firefighting with Redis counters
- Manual rate limiting scripts that break
- No visibility into who's abusing what
- No way to enforce fair usage across all clients
After
Transparent policies, predictable costs, stable performance
- Policy-driven limits with YAML/UI editor
- Real-time enforcement at the edge
- Protected APIs with intelligent throttling
- Traffic is distributed by policy.
Key Capabilities
Built for different roles, unified by fairness
Policy-Driven Limits
