About StackBlitz and Relic.space

In their own words, as submitted to SaaSHub.

StackBlitz
Relic.space

No description of StackBlitz yet.

Relic keeps a permanent, searchable history of everything you copy. It runs locally first: your clipboard history lives in an end-to-end encrypted vault on your own machine, with full-text and semantic search, OCR for images, and automatic masking for values that look like secrets. Optional sync...

Features and specs

What each product offers, as listed by its team.

StackBlitz 6 features
Relic.space 11 features
  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.
  • WebContainers
    StackBlitz uses WebContainers to run Node.js applications in the browser, providing a near-native development experience.
  • Collaboration
    Real-time collaboration features allow multiple users to work on the same project simultaneously, similar to Google Docs.

Possible disadvantages

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.
  • Clipboard history
    Every copy is captured instantly and kept permanently until you delete it.
  • End-to-End Encryption
    History lives in an encrypted vault; sync servers never see plaintext.
  • Cross-device sync
    Optional sync between Windows, macOS, Linux, Android, and iPhone.
  • Local-First Storage
    Everything works offline; the vault sits on your own machine.
  • Full-text and semantic search
    Find items by exact words or by what you remember them meaning.
  • Secret masking
    Values that look like keys or passwords are hidden automatically until revealed.
  • OCR for images
    Text inside screenshots and photos becomes searchable on-device.
  • Self-Hosting
    Run your own sync server; the hosted service is optional.
  • Web vault
    Open, search, and edit your vault from a browser.
  • CLI for agents and scripts
    Read and write the vault from the command line.
  • Open Source
    AGPL-3.0, with the crypto package under Apache-2.0.

Questions & Answers

As answered by people managing StackBlitz and Relic.space.

What's the story behind your product?

Relic.space's answer:

Relic started with a familiar annoyance: you copy something important, and a week later it is gone, so you end up emailing yourself things or digging through chat history. The clipboard turns out to be some of the most sensitive data you produce, so Relic was built local-first and end-to-end encrypted from the start, then grew from a Windows app into apps for all five platforms, a web vault, and a CLI. The whole product was open sourced in August 2026.

What makes your product unique?

Relic.space's answer:

Most clipboard managers keep a rolling history that quietly expires. Relic treats your clipboard as a permanent, searchable vault: everything you copy is kept until you delete it, encrypted end to end, and searchable by meaning as well as by exact text. OCR runs on-device so even text inside screenshots is findable. It is open source, works on Windows, macOS, Linux, Android, and iPhone, and you can sync through Relic's hosted service or your own self-hosted server.

Why should a person choose your product over its competitors?

Relic.space's answer:

Most alternatives are single-platform: Paste and Maccy are Mac only, Ditto is Windows only. Relic covers all five major platforms with one encrypted vault. Sync is optional and end-to-end encrypted, so the server never sees plaintext, and the whole product is open source under AGPL-3.0, so you can audit it or run the server yourself. If you stop paying, your data still lives locally on your machines.

How would you describe the primary audience of your product?

Relic.space's answer:

Developers and power users first: people who copy commands, snippets, keys, and links all day and keep losing them. More broadly, anyone who emails themselves things from one device to open on another, and privacy-conscious people who will not put their clipboard in a cloud they cannot verify.

Which are the primary technologies used for building your product?

Relic.space's answer:

The apps are Flutter and Dart. The on-device AI engine (search embeddings, OCR, image tagging) is Rust with ONNX Runtime. Local storage is SQLite. The sync backend runs on Cloudflare Workers in TypeScript, with the same server available self-hosted on Node. Encryption uses XChaCha20-Poly1305 with Argon2id key derivation.
