ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity โ€” no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

Vitest features and specs

  • Performance
    Vitest is known for its fast performance due to its deep integration with Vite, enabling it to leverage Hot Module Replacement and other optimizations.

Possible disadvantages of Vitest

    While Vitest is designed with modern apps in mind, it may face compatibility issues with some legacy applications or libraries not optimized for Vite.
  • Learning Curve for Non-Vite Users
    Developers who are not familiar with Vite may face an additional learning curve as Vitest leverages many concepts from Vite.

  • Making my TypeScript types 15.7 faster
    I used to use ts-expect for this, but I migrated to Vitest's type-testing utils (expectTypeOf, above) to drop a dependency. Either way, I already had the tests, and I'll admit they really earned their keep. A type optimization can quietly turn { a: string } into { a?: string } and nothing throws. The tests are what catch that. - Source: dev.to / about 1 month ago
  • 7 Free Tools for Testing AI-Generated Code Before It Ships
    Vitest is a newer testing framework designed specifically for projects using Vite as a build tool. If your project already uses Vite, Vitest is worth knowing about because its test runner is significantly faster than Jest's in that context. - Source: dev.to / 3 months ago
  • Three Ways to Convert JSON to TypeScript. Only One Is Deterministic.
    Test fixtures. If you write tests with Jest or Vitest, converting fixture files ensures your mocks match production shapes. - Source: dev.to / 3 months ago
  • oxlint-tailwindcss: the linting plugin Tailwind v4 needed
    The project runs entirely on the VoidZero tool ecosystem. Tsdown for the build, oxfmt for formatting, vitest for testing, tsgo (native TypeScript 7 in Go) for type checking, and of course oxlint for linting the plugin itself. Every tool in the chain is built on Rust or optimized for speed. - Source: dev.to / 4 months ago
  • VoidZero is driving the unification of the Javascript ecosystem
    VoidZero launch week is drawing to a close, and the world of Javascript development has just been given a significant boost. If you follow developments in build tools, youโ€™ll know that fragmentation is rife, and that itโ€™s difficult to stay at the cutting edge without using the best tool for each task. With the latest announcements regarding Vite, Oxlint and Vitest, Evan You team is taking a major step towards the... - Source: dev.to / 4 months ago
