Nanonets
Pros
- + Block-based pricing is the clearest cost model in the category: $0.02 simple / $0.10 standard AI / $0.30 complex AI per run — my four-block invoice test cost roughly $0.52 per document at list rates
- + $50 in free credits with no card makes real evaluation possible: I ran production-shaped documents before spending anything
- + Workflow layer with validation blocks catches extraction errors (a smudged quantity field in my test) before they reach downstream systems
- + Extraction handles the hard cases — multi-page invoices with line-item tables and nested fields — with only one field-level error on my messy sample
- + Breadth of ingestion: API, web upload, email forwarding, cloud storage connectors, and ERP/database integrations on Growth
Cons
- - Billing is per block run, not per page — workflows with many validation retries can multiply cost in ways per-page pricing would not
- - Growth and Enterprise pricing is quote-only, and the 'up to 40% volume discount' is negotiated rather than published
- - Starter caps at three users with community support and excludes premium blocks (classification, barcode/signature, generative AI, custom Python)
- - Fax-grade scans and handwriting still need human review; legible print-style annotation is the practical ceiling
- - Compliance features (HIPAA posture, regional data residency) are Enterprise conversations — not available self-serve
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
