Overview
Deta Surf is a notebook you download that puts browsing, reading and note-taking in one place. Notebooks collect websites, images, files, notes and media, and you can ask questions across them, get summaries and deep dives, and build small interactive applets ('Surflets') without code. Notes include citations linking to the source, and data is stored locally.
- Best for
- Researchers who read across tabs, PDFs and video and want their notes in the same app.
- Pricing
- The captured pages show no prices or plans — only a download link for the open beta.

- Only the core source is open; the rest is unstated
- Requires a download; no web or mobile version mentioned

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
