As answered by people managing Marker.io and Buglesstack.
Buglesstack's answer:
Buglesstack's answer:
Unlike generic error trackers, it captures visual crashes, HTML, and context-specific logs from tools like Puppeteer or Playwright—making debugging fast, visual, and actionable. No extra setup. No noise. Just answers.
Buglesstack's answer:
Buglesstack was originally built as an internal debugging tool for afipsdk.com, a platform that automates government API interactions using headless browsers. After solving real-world issues in production scraping and automation, it evolved into a standalone solution for developers using tools like Puppeteer, Playwright, Selenium, and Cypress. Today, Buglesstack serves engineers who need reliable, visual debugging for browser automation at scale.

It captures crash screenshots, HTML snapshots, and stack traces to help developers detect, log, and fix errors in headless browser scripts.
Buglesstack's answer:
Buglesstack’s primary audience is developers and automation engineers who build and maintain browser automation scripts using tools like Puppeteer, Playwright, Selenium, or Cypress. This includes:
- 🧑💻 Web scrapers who need to debug flaky selectors and page timeouts
- 🧪 QA engineers running headless browser tests in CI pipelines
- 🏗️ Automation teams maintaining bots for tasks like form submissions, screenshots, or data extraction
- 🚀 DevOps or SREs monitoring browser-based jobs for stability and uptime
They value fast debugging, visual context, and low-friction integration

Buglesstack is built using a modern, scalable tech stack:
- Node.js – for backend services and Puppeteer-based job handling
- Astro – for fast, lightweight frontend rendering
- PostgreSQL – as the primary relational database
- Heroku – for app deployment and job orchestration
- AWS Amplify – for frontend hosting and CI/CD
- AWS SES – for reliable transactional email delivery
