What it is
Cloudflare Workers is the platform Moltworker deploys to. Genuine free-tier viability for low-volume self-hosted agents.
Why we use it
- Generous free tier for low-volume agents
- Sub-millisecond cold starts
- Edge deployment across 330+ locations
- Unified developer experience with Cloudflare's broader stack
Why we wouldn't
- Workers runtime constraints rule out many agent capabilities (no native binaries, no long-running processes, no browser automation)
- Lock-in to Cloudflare's stack
- Less flexible than VPS for unusual setups
Best for
- Low-volume agents that fit Workers runtime constraints
- Cloudflare-native shops
- Edge-deployed scenarios where geo-distribution matters
Not for
- Browser automation workloads
- Long-running agent processes
- Anything needing native dependencies
Long review
Cloudflare Workers earns its place in this list because the free tier is genuinely usable for small self-hosted agents — 100K requests per day on the free plan covers a serious personal deployment. Workers' V8 isolate model means sub-millisecond cold starts and global edge distribution “for free”. The catch is the runtime: no native binaries, no long-running processes, no browser automation. For an agent that's mostly LLM calls + lightweight HTTP tools, Workers is fantastic. For anything heavier (the typical Hermes Agent setup with browser automation), Workers can't host it. Moltworker exists specifically to make Workers viable for the constrained-but-meaningful case. We don't have an affiliate relationship with Cloudflare but we do use Workers ourselves for some smaller projects.
