About this category: Coding-tool focused

This category is organised not by model but by how you use it: these services are adapted specifically for AI coding clients — Claude Code, Codex CLI, Cursor, Cline, Roo Code, Continue and others.

"Adapted" means three specific things: supporting the protocol the client speaks (Anthropic native or OpenAI Responses); handling streaming properly, since coding is unusually sensitive to time-to-first-token; and supporting tool calls with long context, because a codebase context easily runs to hundreds of thousands of tokens. Miss any one of them and the client will misbehave on a real project — often not at the start, but once the context grows.

The most useful reference when choosing is what other people have actually run through it. Our verification status and API probe results can rule out services that plainly do not support the protocol, but in the end you should test with your own project.

Pay attention to the pricing model as well. Coding tools consume tokens continuously and in volume, so the difference between a subscription (a fixed monthly allowance) and pay-as-you-go becomes very visible under heavy use. Estimate your monthly usage before choosing.

How to choose within this category

The picks below are computed live from the current measurements, not fixed conclusions — change the data and the picks change with it. Each states its basis, and you can open the detail page to check it yourself.

  • Most stable:Highest current uptime. Fewer samples means more distortion, so we state the source (public dataset / our own measurement) and you can check it on the detail page.
  • Fastest:Ordered by the home-page response time of the most recent probe. A single measurement is noisy, so treat it as a range rather than an absolute.
  • Broadest model coverage:This uses the model count our endpoint probe actually detected, not the support list the service advertises — the two are measured differently, and the advertised figure is usually the more optimistic one.

Frequently asked questions

The questions we see most often about this category. The guidance applies to the category as a whole, not to any single service.

How do I confirm a relay supports Claude Code or Codex CLI?

Check the protocol, not the marketing copy. Claude Code needs /v1/messages; Codex CLI needs /v1/responses. Send one minimal request to each endpoint — a normal response means the protocol is implemented. Our detail-page probe results are a reasonable first filter.

Why does streaming matter so much for coding?

Because perceived latency in a coding tool is mostly time-to-first-token. If a service buffers the whole response before returning it, the editor feels sluggish even when the total time is identical. Test by sending a request that produces a long answer and watching how quickly the first character arrives.

Will long context get truncated in coding work?

It is one of the easiest traps to fall into. Context grows fast as a project grows, and some services behave perfectly on short requests until the context gets long, then start erroring or dropping content. Test with your own project in its later stages, not with a hello world.

Subscription or pay-as-you-go — which works out cheaper?

It depends on how steady your usage is. Large, steady volume makes a subscription cheaper at the margin; volatile usage, or a fresh start, makes pay-as-you-go safer because you are not paying for an allowance you never use. Convert last month's actual consumption into both models before deciding.
