As answered by people managing Smartlook 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.
Buglesstack's answer:
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's answer:
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
This stack ensures performance, reliability, and easy scaling for debugging browser automation workloads.
