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.

Pydantic

API service

Pydantic AI GatewayAPI service

LLM proxy that gives an application one key for OpenAI, Anthropic, Google, Groq and AWS Bedrock models, passes each request through in the provider's native format, caps spend per project, user or API key by day, week, month or total, and sends OpenTelemetry traces of every call to Logfire or any other backend, with a cloud dashboard or a self-hosted deployment.

No counterpart

Browserbase sells these in a stack layer with no product recorded for Pydantic yet — nothing on the other side to compare them against.

Application

DirectorApplication

Director turns plain-English instructions into browser agents that can run on a schedule.

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.

Pydantic sells these in a stack layer with no product recorded for Browserbase yet — nothing on the other side to compare them against.

Developer tool

Pydantic AIDeveloper tool

Open-source Python framework for building typed AI agents that call tools and subagents, validate tool arguments and structured outputs and retry when a check fails, keep a plan, workspace and memory through the Pydantic AI Harness package, and resume long runs on a durable runtime such as Temporal or DBOS, with models from OpenAI, Anthropic, Google, Bedrock, Mistral, Groq or Ollama.

Pydantic LogfireDeveloper tool

Pydantic Logfire collects application traces and evaluates AI outputs to help developers investigate failures and verify changes.
