## Tabstackとは？

Tabstack is a managed web API built by Mozilla for applications and agents that need results from live websites. It handles the work between finding sources and producing usable output: reading pages, filling information gaps, reconciling conflicting sources, and assembling cited answers.

Developers can also request clean Markdown, JSON matching a defined schema, or completion of a task on a public website. The web workflow runs outside the calling model, so applications can consume the result without maintaining their own search, rendering, parsing, and citation logic.

## Tabstackでできること

### Research with citations

Research plans queries, retrieves and reads sources, searches again to fill gaps, and synthesizes an answer with claim-level citations. Fast and Balanced modes are available according to plan.

### Page extraction and rendering

Extract fetches and renders pages, including JavaScript-heavy sites, and returns clean Markdown with boilerplate removed or JSON that follows the requested schema.

### Derived structured data

Generate fetches a page and uses AI to transform its content into derived or reshaped JSON, supporting outputs beyond direct field extraction.

### Hosted browser tasks

Automate navigates and interacts with public websites from a starting URL and natural-language task. It returns the result with task events.

### SDKs and native agent tools

Access Tabstack through Python, TypeScript, HTTP, or a CLI. Integrations include LangChain, Vercel AI SDK, OpenAI Agents, Claude Agent, Mastra, LlamaIndex, eve, and Hermes Agent.

## 利用シーン

### Research current technical changes

Give an assistant a question about release changes or current documentation and receive a sourced answer for evaluating deployment decisions.

### Maintain a knowledge base

Extract readable content from a source set for a knowledge base, using repeat extraction calls to keep referenced material current.

### Collect typed product records

Define fields such as a product price and extract matching JSON from a page for use in an application’s data workflow.

### Delegate public-site navigation

Ask an agent to find a fare or complete another public web task through hosted browser interactions, without running a browser locally.

## よくある質問

### How can I evaluate Tabstack?

New accounts receive 10,000 free credits without a credit card. These can be used across Research, Extract, Generate, and Automate. At published rates, they cover 1,000 Markdown extraction calls or 40 Fast Research actions; a research task may involve multiple actions.

### How do paid plans differ?

Starter costs $10/month for 100,000 credits and 15 requests/minute. Team costs $99/month for 500,000 credits and 25 requests/minute. Pro costs $499/month for 3,000,000 credits and 100 requests/minute. All include every endpoint; Starter offers Fast Research, while Team and Pro also offer Balanced. Overage costs $0.30 per 1,000 credits on Starter and Team, or $0.25 on Pro, subject to account caps.

### Can hosted automation sign in to accounts?

No. Hosted Automate is limited to public websites and cannot log in. Pilo, Tabstack’s open-source automation engine, provides a self-hosted path when you need control of the browser.

### How is customer data handled?

Tabstack does not train models on customer payloads. Detailed data collection is off unless the account opts in. Hosted Automate sends task text and page content to a contracted model provider.

### Can I use Tabstack with a model I control?

Yes. Tabstack supports applications using models on local hardware, in a private cloud account, or through a provider while retaining control of the application layer.
