Terms of Use
By using DevToolChain you accept these terms.
Last updated: September 29, 2026
Using the site
DevToolChain is free to use and needs no account. Please do not misuse the site, for example by trying to disrupt it or by placing an unreasonable load on it.
General information, not professional advice
The content and the results of the tools are general information. They are not professional advice.
Check important results yourself before you act on them. In particular, the JWT decoder verifies only HMAC signatures and only with the secret you enter, a self-signed certificate is for testing and is trusted by nobody until you install it, the contrast checker does not establish that a design is accessible, and a matching checksum does not establish where a file comes from.
You are responsible for what you enter into the tools, including for observing the rules of your organization about credentials and confidential data.
