RendShot

One API call turns your HTML/CSS into a pixel-perfect PNG, JPEG, or WebP. No Puppeteer, no Docker, no headless browser to maintain. Ship an MCP server so Claude/Cursor can generate images as a tool call. Or just describe what you want in a prompt. Design templates once, render thousands of variations with variables. REST API, TypeScript SDK, Python SDK, CLI — all open source. Sub-2s rendering. Free tier: 100 images/month. No credit card.
