PageBolt — The Web-Capture API That Records Narrated Walkthroughs

Developers can automate visual workflows and generate narrated demo videos through PageBolt, an API platform that consolidates seven distinct capabilities under a single authentication key. The service handles screenshot capture across more than 25 device presets ranging from iPhone SE to Galaxy S24 Ultra, PDF generation, OG image creation, browser automation sequences, and video recording with AI voice narration. The platform's signature feature is Audio Guide, which enables automated creation of narrated demo videos for pull requests. When integrated into CI/CD pipelines through a single YAML file, an AI agent reads pull request changes, visits preview deployments on platforms like Vercel or Netlify, and records polished demo videos with professional voice narration. These videos post automatically as PR comments without manual intervention. The narration engine uses Azure AI Speech and OpenAI TTS, offering voices including Ava, Andrew, Emma, and Brian with speaking styles ranging from professional to cheerful and friendly. Users can add narration to individual steps or write continuous scripts with timeline markers. PageBolt distinguishes itself through its Model Context Protocol server, which enables Claude, Cursor, and Windsurf to execute visual capture commands directly from natural language prompts. Developers can request "record a demo of our checkout flow" within their IDE, and the finished narrated video appears in the chat interface without leaving the development environment. The MCP integration extends beyond video to screenshots, PDFs, page inspection, and OG image generation. The platform addresses common headless browser limitations by offering stealth mode to bypass bot detection walls and proxy routing options. Managed browser pools eliminate the need to maintain Chromium installations, while automatic blocking handles cookie consent banners from OneTrust, CookieBot, and over 30 providers. Video recording, encoding, and format handling require no configuration. PageBolt offers a free tier providing 100 requests monthly with access to all seven APIs, 20-second video recording, and a 10 requests per minute rate limit, requiring no credit card. Paid plans scale from $10 monthly for 500 requests to $200 monthly for 100,000 requests, with graduated rate limits and extended video durations. A pay-as-you-go option exists without monthly commitments. Official SDKs support Node.js and Python, though the service operates through standard HTTP requests compatible with any programming language.
