Question 1

What is Spoold?

Accepted Answer

Spoold is a free, privacy-first developer toolbox. Paste into the Magic Box and it detects JSON, HTML, JWT, curl, OpenAPI, CSV, timestamps, and more—then suggests the best tool. You can also browse the full catalog by category. No sign-up is required.

Question 2

Is Spoold free to use?

Accepted Answer

Yes. Core tools are free. Heavy work runs in your browser so your payloads are not processed on Spoold servers for formatting, decoding, and similar utilities.

Question 3

Is my data safe with Spoold?

Accepted Answer

Tool processing for supported client-side utilities happens in your browser. Encrypted share links are designed so only people with the link can read the payload. Review the Privacy Policy for details on local storage, analytics, support, and third-party services.

Question 4

What tools are available?

Accepted Answer

Spoold ships 86+ tools including JSON formatter and diff, JSON Schema validation, YAML and TOML converters, HTML and Markdown preview, JWT decode and sign, OpenAPI/Swagger viewer with curl, GraphQL formatter, curl to code and curl compare, certificate viewer, CSV preview, regex tester, Mermaid, code editor, LLM token utilities, QR codes, and many encoding and text utilities.

Question 5

Is Spoold ad-free?

Accepted Answer

Yes. Spoold uses optional support and in-layout promotions for its own tools instead of third-party ad placements. You can support development from the Support Spoold page.

Question 6

Can I use keyboard shortcuts?

Accepted Answer

Yes. Press Cmd or Ctrl+K to open tool search, use / from the homepage, and use per-tool shortcuts (shown in the UI) such as jj for JSON and hh for HTML where configured.
