Products, side by side

Algorithmic pairing — assembled from recorded fields, not hand-checked

Browserbase

API service

Browserbase Fetch APIAPI service

API that reads a URL live at request time and returns it as clean markdown, HTML or JSON for an agent's context, with ads and navigation stripped and an Extract option for structured fields.

Browserbase Model GatewayAPI service

Routes a Stagehand agent's model calls to OpenAI, Anthropic and Gemini through the Browserbase API key, handling billing, retries and rate limits, with tokens charged at the providers' own prices.

Browserbase Search APIAPI service

Real-time web search API for agents that returns ranked, token-optimised results (URL, title and favicon per page) so an agent can pick which sites to fetch or browse next.

AI agent

Browserbase AgentsAI agent

Managed browser agent created from a natural-language prompt and run with one API call; it navigates sites, fills forms and returns structured JSON, with browsers, search, verified identity and proxies included.

Infrastructure service

BrowserbaseInfrastructure service

Cloud browsers, search, fetch and a managed runtime that AI agents use to browse, fill forms and act on websites, with session replays for debugging.

Browserbase IdentityInfrastructure service

Gives each Browserbase session a cryptographically verified agent credential through Web Bot Auth, so partner sites and anti-bot providers let the agent in, with CAPTCHA solving and reusable logged-in contexts.

Browserbase ObservabilityInfrastructure service

Debugging view over every Browserbase agent session: live view, action-by-action replay, structured logs of network requests, console output and errors, and traces of each agent decision.

Browserbase RuntimeInfrastructure service

Sandboxed, isolated hosting for agent code deployed to Browserbase (Browserbase Functions), so an agent runs next to the browser session it controls instead of on a separate server.

Mastra

API service

Mastra GatewayAPI service

An OpenAI- and Anthropic-compatible model gateway that routes one API key to 300+ models with provider failover, and adds observational memory that compresses each conversation into notes so agents keep context without rebuilding it.

AI agent

Mastra CodeAI agent

An open-source terminal coding agent with Build, Plan and Fast modes and explore, plan and execute subagents, whose observational memory compresses the session into notes instead of compacting it, so long sessions keep their context.

Mastra FactoryAI agent

An open-source software delivery environment where coding agents take a connected repository's issues through investigation, planning, implementation and review to a reviewed pull request, with people deciding at each step; self-hosted or deployed on Mastra's platform.

Infrastructure service

Mastra Platform ObservabilityInfrastructure service

Hosted telemetry store for Mastra agents in production: it keeps the metrics, structured logs and step-by-step traces of model calls, tool calls and workflow steps for every run, with dashboards for cost, latency and quality scores.

Mastra ServerInfrastructure service

Hosted deployment target that runs a Mastra application's agents, tools and workflows as an API server from one command, with routing and scaling handled by Mastra and billing by CPU time and data egress.

Agent platform

Mastra Agent BuilderAgent platform

A UI mounted inside a team's own Mastra server for creating and operating internal agents, with multi-tenant workflows, role-based access and channel integrations, licensed for production under Mastra's enterprise licence.

Developer tool

MastraDeveloper tool

An open-source TypeScript framework that developers use to build, run and observe AI agents and workflows, with a hosted Studio and cloud deployment option.

Mastra StudioDeveloper tool

A shared workspace where a team inspects agent runs through traces and cost, latency and quality metrics, scores outputs with LLM-as-judge or code, runs dataset experiments and versions prompts and agent configurations, open to non-engineering reviewers without source access.
