“The demo server of CORS Anywhere (cors-anywhere.herokuapp.com) is meant to be a demo of this project. But abuse has become so common that the platform where the demo is hosted (Heroku) has asked me to shut down the server, despite efforts to counter the abuse (rate limits in #45 and #164, and blocking other forms of requests).

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Frontend developers needing cross-origin API access represent modest, concrete demand of ~10 monthly searches—a small, steady user base with a real friction point.
Competition & the opening
1/10 competition with no named competitors is surprising given CORS Anywhere's visibility; the opening is in reliability, SLAs, and commercial support where the free demo fails.
What's hard to build
Operating a stable proxy at scale requires robust request filtering, DDoS mitigation, and origin validation; you must prevent abuse while maintaining performance—all infrastructure-heavy and operationally fragile.
Why now
Public CORS proxies are dying due to abuse; companies need a reliable paid alternative with SLA guarantees.
