Developer tools, ready when you are.

Useful transformations without the upload step

DevBloom keeps everyday developer utilities together: clean up JSON, move between JSON and YAML, compare revisions, encode text, inspect JWT claims and create SHA hashes.

Your data stays in the browser

All processing happens locally with JavaScript. Inputs are not transmitted to inblooms or saved on a server. Avoid pasting production secrets into any website, and remember that decoding a JWT does not verify its signature.

How to use DevBloom's developer tools

DevBloom bundles the small utilities developers reach for many times a day into one fast, private page. Paste your data, get a result, copy it — nothing is uploaded. Here is a quick tour of what each tool does and when to reach for it.

JSON format, minify and validate

Paste messy or minified JSON to pretty-print it with consistent indentation, or minify it to the smallest valid form for shipping. If the JSON is invalid, DevBloom points to the problem so you can fix a stray comma or bracket, and sorting keys makes diffs and code reviews easier to read.

JSON and YAML conversion

Convert configuration between JSON and YAML in either direction — handy when one tool wants YAML but your data is JSON, or the other way round. It handles the common shapes (objects, arrays, strings, numbers and booleans) that most config files rely on.

Base64 and URL encoding

Encode or decode Base64 and percent-encoded URL strings. The encoding is Unicode-safe, so emoji and non-Latin text round-trip correctly — useful for data URIs, query parameters and quick token inspection.

JWT decoder, text diff and SHA hashes

Decode a JWT to read its header and payload and check expiry without sending it anywhere — note this does not verify the signature. Compare two blocks of text line by line to spot changes, and generate SHA-256, SHA-384 or SHA-512 hashes with the browser's Web Crypto API.

Common DevBloom workflows

Clean an API response before debugging

Paste a raw API response into the JSON tool, format it, then sort keys when you need stable screenshots, tickets or code-review diffs. If parsing fails, the error points to the place to check first instead of silently changing your data.

Move small config snippets between formats

Use the JSON to YAML converter for ordinary configuration objects, arrays and scalar values when copying settings between tools. For advanced YAML with anchors, aliases or custom tags, keep your source file in a dedicated editor and treat DevBloom as a quick scratch converter.

Inspect tokens and fingerprints safely

The JWT panel is useful for reading claims such as issuer, subject, audience and expiry before you debug an auth flow. The hash tool creates one-way SHA fingerprints for comparing text or file metadata, while Base64 and URL encoding help check query strings and payload fragments.

What each DevBloom tool is best for

The six panels overlap a little, but each one has a different job. These notes help you pick the right tool and avoid common mistakes when working with real developer data.

JSON formatter and validator

Use JSON formatting for API responses, config fragments, webhook payloads and logs. Sorting keys is helpful for stable diffs, but it can change the original key order, so keep an untouched copy when order carries meaning for documentation.

JSON to YAML converter

Use the YAML converter for common config shapes: objects, lists, strings, numbers and booleans. It is intentionally simple and does not try to preserve comments, anchors, aliases or custom YAML tags.

Text diff checker

Use the diff panel to compare before-and-after snippets, release notes, config edits or translated strings. Turn on whitespace ignore when indentation noise hides the meaningful line changes.

Base64 and URL encoding

Use encoding tools to inspect query strings, callback URLs, small data URI fragments or text that needs safe transport. Encoding is not encryption: anyone can decode Base64 or percent-encoded text.

JWT decoder

Use the JWT decoder to read the visible header and payload claims, including expiry, issuer and audience. It does not verify signatures, so a decoded token is not proof that the token is trusted or still accepted by your server.

SHA hash generator

Use SHA-256, SHA-384 or SHA-512 hashes to create repeatable fingerprints for text comparison or integrity notes. A tiny change in spaces, line endings or casing produces a completely different hash.
