Tabstack
Tabstack is Mozilla's web layer for AI agents - a developer API that turns web pages into clean data and runs browser-style actions without you managing headless Chrome. It exposes a small set of endpoints: extract converts a URL into markdown, JSON, or a custom schema; generate reshapes that data; automate performs interactions; and research sends agents to explore sources and return answers. It routes requests dynamically, using lightweight fetches first and spinning up full browser sessions only when JavaScript demands it. Being Mozilla, the privacy stance is explicit: it does not train on your data, and retrieved pages are purged after the call. There is a free trial, then pay-as-you-go at $0.35 per 1,000 credits, a $99 Team plan, and a $499 Pro plan.

Our take
Tabstack is Mozilla's browser-and-extraction API for AI agents: extract, generate, automate, and research endpoints that skip the headless-Chrome plumbing and return clean, LLM-ready data. It scales from cheap fetches to full browser sessions only when needed, and Mozilla's no-training privacy stance is a real differentiator. Free trial, then transparent pay-as-you-go from $0.35 per 1,000 credits.
Best for
Developers building AI agents that need to read the live web and take browser actions without running their own scraping stack.
Pros
- Extraction and browser automation in one API
- Returns clean, LLM-ready markdown or JSON
- Mozilla-backed with an explicit no-training privacy stance
- Transparent pay-as-you-go pricing
Cons
- Developer-facing, not a no-code product
- New entrant in a busy web-data space
- Costs scale with heavy browser use
How it compares
Against scraping APIs like Firecrawl or browser tools like Browser Use, Tabstack bundles extraction, automation, and research under Mozilla's privacy posture.

NotebookLM
Google's source-grounded research assistant: upload docs, PDFs and links, then ask questions, generate study guides, and turn sources into audio and video overviews. The free tier is genuinely usable; Plus raises the limits.
OpenRouter
OpenRouter is a unified API and marketplace for large language models. With one account and key you can reach 300+ models from OpenAI, Anthropic, Google, Meta, Mistral, Cohere and many smaller providers, using an OpenAI-compatible interface. It charges passthrough rates (provider cost plus a small markup) and publishes live pricing and usage-based model rankings, so you can compare options and route to the cheapest, fastest or most reliable one. It supports automatic fallback across providers and a free-model tier for experimentation; the main costs to watch are a 5.5% credit-card fee, which hits small top-ups hardest, and a 5% bring-your-own-key fee on requests above one million per month.
