Tinker Less With Tools.
Build More Software.
From Base64 and JWT decoding to JSON formatting, hashing, UUID generation, and data transformation, TinkerDev puts practical developer tools in one convenient place — so you spend less time on busywork and more time creating.
- Native macOS
- Works offline
- Your data stays local
- Keyboard-first

Instant
Paste and it answers — decodes land in well under a second. No spinners, no waiting.
Private by design
Your inputs are processed locally and never leave your machine. The only network calls are a license check and optional update checks — never your data.
Keyboard-first
Hit ⌘K to jump to any tool. Built for hands-on-keyboard developers who hate hunting for tabs.
Native & light
A true native macOS app built on Tauri — tiny download, low memory, no Electron bloat.
The standout
Decode Protobuf with no .proto in sight
Paste raw Protobuf bytes — hex, base64, or decimal — and TinkerDev lays out every field number, wire type, and nested message. No schema, no guesswork. The fastest way to understand a payload you've never seen before.
- Schema-less: works on any wire-format blob
- Nested messages expand into a clean tree
- Toggle field interpretations (varint, LEN, packed…)
- Copy any field — or the whole thing — as JSON

Everyday utilities
The transforms you do a dozen times a day
Hashing, encoding, decoding, parsing, formatting, generating. The small tasks between writing code — handled in one fast, consistent workspace instead of a dozen sketchy websites.
- MD5 & SHA-1/256/384/512 in one paste
- JWT, Base64, URL, JSON & XML — decode and inspect
- Generate UUIDs, ULIDs and test data on demand
- Consistent, copy-anything output everywhere

One app, many utilities
The tools you reach for, all in one place
Every tool is one ⌘K away — no tabs, no websites, no terminal incantations. And the collection keeps growing.
