As answered by people managing HeyGen and CaptureAPI.dev.
CaptureAPI.dev's answer:
Named customer references available on request as the user base grows.
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.
