About

KERNEL is a cloud browser infrastructure platform for developers building AI agents and browser-based automation. It provides managed browser sessions that agents can use to navigate websites, interact with page content, and perform tasks through code rather than relying on a local browser setup. The service is designed for production workloads, with persistent browser profiles, live browser viewing, session recording and replay, and controls for managing browser access. Teams can connect agent workflows through KERNEL's APIs, SDKs, and hosted MCP server, and use the platform for web research, data gathering, and other tasks that require interacting with websites. Plans for individual developers, startups, and enterprise teams include different browser concurrency, usage credits, and access to capabilities such as managed authentication, stealth mode, and regional browsers.

About

Tabstack is a managed web API that helps developers extract data, generate structured outputs, run live-web research, and automate browser tasks through simple API calls. The platform lets users pass a URL, schema, question, or task and receive schema-matched JSON, clean Markdown, cited answers, or completed browser actions without managing an LLM, browser, scraper, or orchestration pipeline. Its endpoints support structured extraction, Markdown extraction, JSON generation, live research with citations, and web automation across JavaScript-heavy pages. Developers can use Tabstack for competitive intelligence dashboards, lead enrichment, research agents, booking and checkout agents, workflow automation, and knowledge base ingestion. The platform includes SDKs for TypeScript and Python, MCP support, CLI tools, streaming research results, human-in-the-loop automation, and privacy-focused data handling. With free credits, pay-as-you-go pricing, team plans, and enterprise options, Tabstack
