Overview
OpenNotas is an open-source, PWA-based note-taking app for phones and desktops, covering Windows, macOS and Linux. Notes are encrypted with AES on the device before reaching a sync server, and the secret key never leaves the device. Sync is set up through pluggable adapters — Turso, S3-compatible storage, or local-only — so you choose where the data is stored.
- Best for
- Individuals wanting a simple cross-platform note app with end-to-end encryption and self-chosen sync
- Pricing
- The pages call the app free and open-source but show no prices, plans or paid tiers.
Strengths and trade-offs
Strengths
- Open-source; runs on Windows, macOS, Linux and mobile
- AES end-to-end encryption, with the key kept on your device
- Pluggable sync adapters: Turso, S3-compatible storage, or local-only
- Works offline and needs no account to start writing
Trade-offs
- Sync requires configuring an adapter and bringing your own backend
- Personal note-taking only; nothing stated about teams or shared notes
- Deliberately minimal, with no organisation or editing features described

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.
