As developers, we often need quick tools for formatting JSON, encoding and decoding data, inspecting tokens, working with SQL, and handling everyday development tasks.
Instead of installing a separate application for every small job, having a collection of handy web tools can save time during development.
A Collection of Free Online Developer Tools
I've been building Vamriko, a website that brings together useful online tools for developers and everyday tasks.
The developer tools collection includes utilities for working with:
- JSON and data formats — format and inspect structured data.
- Encoding and decoding — handle common data transformation tasks.
- JWT and security utilities — work with tokens and related development tasks.
- SQL and development utilities — simplify common coding workflows.
- Networking and DevOps — access practical utilities for technical tasks.
The goal is to make these tools easy to access directly from a browser when you need them.

I'd love to hear from other developers:
Which small development task do you find yourself repeating most often, and what tool do you use to handle it?
I'm continuing to improve the collection and would appreciate constructive feedback.
Disclosure: I'm the creator of Vamriko, and I'm sharing this project transparently.
