A real editing engine that renders in the browser.
Creatomate turns templates into rendered video and images from an API, with a JS preview SDK on top plans. Rendley gives you a real in-browser editing engine, a REST API with a prompt-to-video agent, and an official MCP server, so automation and hands-on editing live on one platform.
Creatomate is a polished media-automation API built around templates, bulk generation, and no-code tools like Zapier and Make. Rendley covers the same programmatic rendering but adds a true client-side editing engine (@rendley/sdk), a deterministic REST API with a /agent/sessions prompt-to-video endpoint, and a first-party hosted MCP server, so you are not limited to filling in template slots.

Creatomate is optimized for producing many variations of a template. Rendley’s SDK is a general editing engine you drive in code, so you can build arbitrary timelines rather than only populating predefined slots.
Both let you embed a preview in the browser. Creatomate’s JS Preview SDK is a template preview available from the Growth plan up; Rendley’s SDK is the actual editing and rendering engine, on every plan.
Both return finished files from a REST call. Rendley adds a prompt-to-video agent endpoint and a deterministic edit spec, plus a first-party MCP server; Creatomate leans on no-code integrations and third-party MCP wrappers.
Rendley aggregates 25+ AI models inside a project and keeps assets on EU storage. Creatomate focuses on template rendering and auto-deletes rendered output after 30 days.
