Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Crun is a cloud API gateway for generative AI from CRUN TECHNOLOGY LIMITED in London. One account and one API key reach more than 100 video, image, audio, music and language models, from providers including OpenAI, Google, Anthropic, ByteDance, Kling, Vidu, Runway and Suno, with a browser playground for trying them.
It is built for developers who ship multimodal features. Requests are OpenAI-compatible, media can be passed by URL, and long jobs run as asynchronous tasks that can be polled or delivered by webhook. Usage logs, rate limits and IP allowlisting are documented, and an agent skill lets Claude Code, Cursor, Codex and OpenClaw route requests, estimate credits, upload files and monitor tasks.
Pricing is prepaid: credit packs cost $5, $50, $500 or $1,250, larger packs give more credits per dollar (200 to 224), and each model call uses credits.
Choose Crun to reach many generative models through one OpenAI-compatible API, paying only for the credits you use.
