Overview
Yaak is a desktop API client for Mac, Windows and Linux that sends HTTP, GraphQL, gRPC, WebSocket and SSE requests in one workspace. It works offline with no account, storing requests and history on the device and encrypting secrets with ChaCha20-Poly1305. Data can optionally be stored as plain text for Git sync, and a CLI and MCP server let agents create and send requests.
- Best for
- Developers wanting an offline, local-first API client with Git-based sharing and a CLI for agents.
- Pricing
- Free for personal use; commercial use needs a licence at $79/year for Individual or $149/user/year for Business, after a 30-day trial.

Strengths and trade-offs
Strengths
- HTTP, GraphQL, gRPC, WebSocket and SSE in one workspace
- Local-only data, zero telemetry, secrets encrypted via OS keychain
- Plain-file Git sync with built-in Git UI and diff viewer
- Imports Postman, Insomnia, OpenAPI and Curl; MIT-licensed
Trade-offs
- Commercial use at work requires a paid licence; free only for personal use
- No built-in AI; agents connect through the CLI or MCP server
- Individual licence is single-user and non-transferable
- No cloud sync — sharing depends on Git, Dropbox or similar

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.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
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.
Pricing transparency
Whether real prices are published, self-serve signup exists, and usage costs are knowable without a sales call.
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.
