Cloudflare Workers alternatives
2 open-source projects that already do this job. Free to use - not free to run, which is what the numbers on the right are for.

What you give up either way
- Global 335+ city edge network and low-latency Smart Placement
- Built-in DDoS/WAF/bot protections and platform security
- Massive scale and uptime SLA
- Integrations and ecosystem (Workers AI, Vectorize, R2, D1) running on the same network
- Operational simplicity of a fully managed, pay-for-execution platform
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Cloudflare Workers, and it does not prove anyone has run it for a month. How we decide.
