Yes — free for everyone. Every tool and every feature, with no paid tier, no trial and no limits.

Is MyDevTools open source?

Yes. MyDevTools is open source under the GNU AGPL v3 — you can read the code, build it yourself, or fork it.

Your data is not sent to MyDevTools servers — there is no cloud sync and no backend. Network tools (API client, database clients) connect only to the destinations you point them at. Vault-style data is additionally encrypted locally with a password only you know.

Do I need an account to use the tools?

No. MyDevTools has no accounts at all — no sign-up, no sign-in, no activation. Download the app, open it, and start working.

Does it work offline?

Yes. MyDevTools is a desktop app — most tools run fully offline on your machine. Tools that connect to external services or send API requests need a network connection.

Do the tools run on this website?

No. This site documents the tools and links to the download; the tools themselves run in the MyDevTools desktop app on your machine. That is what keeps your data local — there is no web app and no server to send it to.

Which databases can MyDevTools connect to?

PostgreSQL, MySQL and MariaDB through the SQL client, MongoDB through the database explorer, Redis through Redis Commander, plus AWS S3 and DigitalOcean Spaces buckets. The drivers are native, so connections go straight from your machine to your database, and credentials are stored encrypted on your device.

Your workflow is fragmented

Your development workflow shouldn't require 10 different tools.

JSON in one tab. API testing in another. MongoDB somewhere else. Redis in another application. A password manager on the side. MyDevTools brings those everyday workflows together — it replaces the fragmentation, not the tools.

One desktop app. Context switching, repeated setup and pasting secrets into random web tools — gone.

Why it exists

I didn't set out to build a developer platform. I just got tired of the tabs.

I kept opening 10+ browser tabs for everyday development tasks. I started building MyDevTools for myself. I added a password manager because I wanted a secure local place for credentials, and a MongoDB client because I wanted a customized way to explore my data.
It started as a web application. Then I started questioning whether sensitive developer data really needed to travel over HTTP in the first place. That pushed me toward an offline-first desktop application.
Friends were also looking for offline-first developer tools, so I kept going. MyDevTools is now an open-source desktop developer workstation with 80+ tools.

80+ tools

Everything you need for everyday development. In one workspace.

Tool breadth is the proof, not the headline. Here is what is actually inside — every link opens that tool's page.

Developer Utilities

The everyday formatters, decoders and generators — offline.

API & Networking

Request collections, environments and sockets in one place.

Databases

Native drivers — connections go straight from your machine to the database.

Security

Credentials and crypto helpers, encrypted locally.

DevOps

Config scaffolding and the small calculators you keep looking up.

Productivity

Project context that stays next to the tools that use it.

Browse all tools

A workstation, not a tool collection

Your project. Your tools. One workspace.

Keep the tools, data, configuration and utilities you use for a project together instead of scattering them across tabs and applications. API collections, database connections, secrets, notes and snippets sit side by side in one local, encrypted database on your machine.

Why offline?

Why send developer data somewhere else if you can process it locally?

MyDevTools Desktop is designed around local-first development. Core tools run on your machine without requiring an account or cloud service.

Local processing

Formatters, decoders, generators and crypto helpers run on your machine.

Local storage

Notes, snippets, collections and credentials live in an encrypted local database.

Offline capability

Core tools work without a network connection. Only the network tools need one.

No mandatory account

No sign-up, no sign-in, no activation. The app opens straight to the dashboard.

No cloud dependency

There is no MyDevTools backend to depend on. Anonymous usage stats are opt-in and off by default.

Your data isn't sent to MyDevTools servers.

Network-enabled tools connect to external destinations only when you explicitly use them, such as an API or database. This website only documents the app and hands you the download — the tools do not run here.
