About TheDevTab
TheDevTab is a set of 31 tools for the small, repetitive jobs that fill a developer's day: reading a JSON payload, checking what is inside a JWT, converting between formats, generating an identifier, or working out why a regular expression is not matching. It is operated by Eksaria. The full list is on the homepage.
TheDevTab is thedevtab.com. It is not a browser new-tab extension, and it is not affiliated with other products named DevTab.
How it works
Every tool runs in your browser. Text you paste and files you drop stay on this device. There is no account, and TheDevTab does not receive that content.
The browser still has limits, especially with very large files. Each tool page says what it does and what it does not do.
There are also written guides for the questions these tools tend to raise.
