CaptureAPI.dev's answer
CaptureAPI bundles website screenshots, HTML-to-PDF conversion, and OG image generation into a single predictable API endpoint. Unlike heavy headless-browser platforms, it offers a 200/month free tier, transparent flat-rate pricing, and a developer-first design with no per-call billing surprises.
CaptureAPI.dev's answer
Three reasons: (1) honest free tier — 200 captures/month, no credit card; (2) flat pricing ($9 / $29 / $79) instead of per-call confusion; (3) screenshot, PDF, and OG image generation all in one API rather than three separate services.
CaptureAPI.dev's answer
Indie developers, side-project builders, and small SaaS engineering teams who need a reliable screenshot/PDF/OG API without enterprise contracts. Common use cases: OG image generation, blog cover screenshots, automated archiving, and product preview generation for landing pages.
CaptureAPI.dev's answer
CaptureAPI was built by an indie maker tired of stitching together Puppeteer scripts, paying enterprise prices for a single feature, and dealing with hidden rate-limit surprises. It launched in early 2026 as part of the DevToolsmith portfolio with the goal of offering screenshot, PDF, and OG generation under one developer-friendly API.
CaptureAPI.dev's answer
Next.js 16, TypeScript, Vercel Functions (Fluid Compute), Playwright for headless rendering, Sharp for image processing, Upstash Redis for rate limiting and caching, Stripe for billing, and Sentry for observability. Serverless on EU + US edge for low latency.
