Listen to this post: The Vibeland Tools Developers Actually Reach For
Development is full of thirty-second jobs. Decode a token to see why auth is failing. Pretty-print a minified API response. Generate a UUID for a seed script. Get a QR code so you can open localhost on your phone. None of them are hard. All of them pull you out of the editor.
The annoyance is not the task, it is the hunt: search, pick a result, wait for the page, dismiss the cookie banner, scroll past the ads, find the box. Vibeland exists to remove that middle part. Below is the subset of its 117 tools that earn a bookmark if you write code for a living.
Decoding and encoding
The JWT decoder is the one most worth pinning. Paste a token, see the header and payload, check the claims and the expiry. When a request is 401-ing and you need to know whether the token is malformed, expired, or simply for the wrong audience, this answers it in one step.
It also runs entirely in your browser. That is not a small detail for this particular tool — a JWT payload usually carries a real user id, a real tenant, real scopes. Pasting one into a server-side decoder means sending a live credential to a stranger’s infrastructure. Here the JavaScript runs on your device and the token never leaves it.
Alongside it: Base64 conversion, URL encoding and decoding for query strings that break on special characters, and HTML entity encoding. The full set lives in encode and decode.
Working with data
The JSON formatter and validator handles the daily case: a response arrives as one unbroken line, you need to find the field that is null when it should not be. It indents the structure and flags syntax errors so you can see where a payload is actually malformed rather than squinting for a missing brace.
When you need to move between formats there is JSON to YAML and back the other way — useful when a config wants one and your source of truth is the other. XML to JSON covers the legacy integrations, CSV to Markdown is quietly excellent for dropping a data sample into a pull request description, and JSON minification trims a fixture before you commit it.
Generating things
The key generators category covers the setup chores. UUID and GUID generation for seeds and test fixtures. A random token generator for API keys in a local environment. Password generation with control over length and character set, for the database user you are about to create and would otherwise name something regrettable.
The mock user generator is the one people tend not to know about. Building a table view and need forty plausible rows rather than “test test test”? It produces them, and your staging environment stops looking like a placeholder.
Front-end odds and ends
The web and developer category holds the CSS helpers: a box shadow generator, a border radius generator, a CSS gradient generator, and a flexbox playground for when you want to see what align-items does rather than remember it.
Two more deserve a mention. The CSS specificity calculator settles the argument about why your override is not applying. And the regex tester does what regex testers do, which is stop you from deploying a pattern you only think works.
For shipping: a meta tag generator, an Open Graph generator for when a link previews badly in Slack, an HTTP status code reference, a URL parser, and a user agent parser.
The mobile testing one
The QR generator solves a specific irritation well: you are running a dev server and you want it on a real handset. Paste the local network URL, generate, scan. No typing an IP address and port into a phone keyboard and getting it wrong twice.
What runs where
Most of these are pure JavaScript executing on your device — the formatter, the decoder, the generators, the CSS tools. Nothing you paste is transmitted, and they would keep working with the network off.
Four tools genuinely need a server, and the site is upfront about which: OCR, background removal, PDF extraction and SSL certificate checking. The first three need models too heavy for a tab; the fourth has to actually reach the host to inspect what it is serving.
That distinction is worth knowing rather than glossing over. It tells you exactly when you are handing data to someone else and when you are not — which is the question you should be asking of any online tool, this one included.
The full catalogue runs to 117 tools across 17 categories, no account, no limits.
