Checksum.ai
Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability.
Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort.
Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in.
Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens.
The result: ship faster, with confidence.

Browser Use provides hosted AI agents and remote browser infrastructure for automating work on websites, including workflows without a usable API.
Browser Use Agents turns natural-language tasks into browser actions for research, form completion, data collection, and document downloads.
Browser Infrastructure gives developers remote Chromium sessions for their own agents, Playwright scripts, or Puppeteer automation. Features include browser stealth, residential proxy options, and automatic handling of supported CAPTCHAs.
The MIT-licensed browser-use Python library lets teams run and customize agents with local or cloud browsers. SDKs, CLI tools, and MCP interfaces connect browser automation to existing applications and agents.
Cloud services use pay-as-you-go pricing with no required subscription. Browser runtime starts at $0.02/hour, with traffic and managed-agent model and service charges billed separately.

Browserless is an advanced web scraping and browser automation platform designed to help developers extract data from protected websites using headless browser technology. The platform uses BrowserQL and browser-level automation to bypass bot detection systems such as Cloudflare and Datadome while enabling reliable access to dynamic web content. Browserless supports HTML and JSON extraction, screenshot generation, browser automation, and session management through APIs and integrations with Puppeteer and Playwright. Developers can automate interactions such as clicking buttons, navigating websites, rendering JavaScript-heavy pages, and maintaining browser sessions for more efficient scraping workflows. The platform also provides WebSocket endpoints, session reconnects, and optimized infrastructure that significantly improves scraping speed and reduces proxy usage.
