Browserbase
Pros
- + Session replay, live viewing and logs turned a failing agent step into a diagnosable one — the debugging surface is the strongest I have used in this category
- + Attaching Playwright over CDP behaved like a local browser in my runs: real rendering, cookie persistence across requests
- + Stagehand (MIT, 25k+ stars) lets agents mix natural-language actions with ordinary Playwright code, and runs locally for free before you need hosted scale
- + Itemized public pricing with a real free tier to prototype on, including $5 in model tokens and 1,000 search/fetch calls
- + Identity features (auto captcha solving from Developer tier, Verified Sessions on Scale) address the part of browser automation that actually fails in production
Cons
- - Six separately metered line items — hours, proxy GB, search, fetch, agent runs, model tokens — so the plan price is a floor, not the bill
- - Proxy sessions carry a 1 MB minimum per session; high-volume tiny sessions pay for data they never moved (~$120 per 10,000 sessions at Developer proxy rates)
- - Stealth tiering is underspecified: public docs never define what 'Basic' excludes versus Advanced/Verified on Scale
- - Free tier is a demo — 1 browser hour/month and 15-minute session caps stopped my first long test exactly at the limit
- - No local-only or self-hosted option for the hosted stack; latency variance versus local browsers is inherent to the model
Stagehand
Pros
- + MIT-licensed SDK runs locally against any Chromium browser; in my test the act() call re-resolved after I rewrote a login button's classes and wrappers, while my hand-written Playwright selector broke
- + extract() returns schema-validated typed data (pydantic/Zod/struct) — pulling an invoice table into typed fields removed the JSON cleanup step entirely
- + observe() hands back real selectors, so I filled login credentials with ordinary Playwright calls and the secrets never reached the model
- + Full TypeScript, Python and Go support from one monorepo, with deep locators that reached nested iframes and a closed shadow DOM in my runs
- + Token cost per action is a fraction of screenshot-driven agents I have tested, because page context is a trimmed accessibility tree rather than images
Cons
- - Every act/extract/observe call is an LLM round trip — my ten-step workflow ran noticeably slower than the equivalent pure Playwright script
- - Code-only: no recorder or visual builder, so non-programmers cannot build or maintain automations
- - Anti-bot features (stealth, residential proxies, verified sessions) live in paid Browserbase plans, not the free SDK
- - Pages with canvas-rendered or heavily obfuscated UIs leave the accessibility tree thin and the AI primitives degrade
- - v4 is still moving fast; I pin versions because major upgrades have meant migration work
