Azure Test Plans vs Cachix

Azure Test Plans gives teams tools to plan, run, and track manual and exploratory testing for apps. For scripted tests, teams can track actionable defects and connect test cases and suites to user stories, features, or requirements. Exploratory sessions let testers design and run tests at the same time. During manual tests, Test Runner can capture screenshots, image action logs, and screen recordings. Reports, dashboard widgets, and customizable Power BI reports show plan progress and trends. The service integrates with Azure Pipelines for CI/CD testing and offers REST APIs and an extension contribution model. Manual testing is available in the web portal through supported browsers on major platforms; a free Test & Feedback extension supports exploratory testing in Chrome and Microsoft Edge. The free Stakeholders plan does not allow users to create or manage Test Plans. Basic is free for the first five users, then $6 per user per month; Basic + Test Plans costs $52 a month, billed at $52 per user per month. A 30-day trial is listed. Azure DevOps cloud-based load testing is deprecated; Microsoft points users to Azure Load Testing for managed load testing.

Cachix hosts Nix binary caches so teams can share binaries across CI, development, and deployment environments. Its CLI can push binaries, watch a Nix store, and configure Nix to use a cache. The service says its optimizations speed up cache roundtrips, while Cloudflare CDN provides performance and unlimited bandwidth on all plans. When a cache reaches its storage limit, least-recently-used entries are removed; Cachix says it sends a warning email at 85% of that limit. Documentation includes CI guides for GitHub Actions, Buildkite, CircleCI, GitLab CI, Hercules CI, Hydra, and Travis CI. Cachix Deploy uses a pull model to deploy continuously to Nix profiles such as NixOS, nix-darwin, and Home Manager. Teams can assign read or write access, revoke tokens, and require a token for private cache reads and writes; cache entries are signed. Enterprise options include on-premise or self-hosted deployment, SSO, SLA, dedicated premium support, custom deployment, and audit logs. Cachix offers a free plan and a 14-day trial. Listed Starter, Standard, and Pro plans have prices available by contacting Cachix.
