Disclaimer

A set of tools, and written explanations of what each one does. It is informational and practical: you paste something in, it comes back transformed, and the page around it explains the transformation.

It is not a service that reviews your work, not a system of record, and not somewhere to store anything — nothing you enter is kept once you close the tab.

Nothing on this site — a tool’s output, an explanation, an answer in a FAQ — is legal, financial, tax, medical, security or other regulated professional advice, and none of it should be treated as a substitute for advice from someone qualified in your situation.

A few tools touch material where that distinction is worth stating out loud. The JWT decoder shows you what a token contains; it does not verify a signature and says so, and it is not a security assessment. A regex tester tells you what a pattern matched against the text you gave it, which is not the same as telling you the pattern is correct.

Review results before relying on them, and especially before anything irreversible. Some sensible habits:

• compare a converted file against the original before discarding the original
• test generated identifiers, expressions or configuration in a safe environment first
• treat a count or a statistic as an indication, not as a certified figure
• keep a copy of anything you paste in — the tool does not keep one for you

The tools are tested against the specifications they implement, and the site is maintained. Even so, software has defects, standards are interpreted differently by different implementations, and a browser may behave in ways a tool does not anticipate. Results are provided without warranty of accuracy, completeness or fitness for any particular purpose.

The site may be unavailable, and tools may change or be withdrawn. There is no guarantee that a tool will behave tomorrow exactly as it does today, although breaking changes are avoided where possible.

Tools marked Runs in your browser process what you paste on your own device; the content is not sent to a bugsTobuild server. That is a statement about tool content, not about the whole of the internet: loading any web page involves a request that carries technical information such as your IP address, and third-party services may be involved where they are enabled.

The privacy policy sets out exactly which services are switched on and what each one receives.

Pages here link to specifications, documentation and other external resources. Those sites are not under our control, and appearing as a link is not an endorsement of their content, accuracy or practices.

Advertising is not currently enabled. When it is, advertisements will be supplied by an advertising network, labelled as advertisements, and their content will not be selected, reviewed or endorsed by us.

Use of this site is at your own risk, and to the extent permitted by law the operator accepts no liability for loss or damage arising from reliance on anything published here. The terms of use set this out in full.
