Developk's Tools is a free collection of developer utilities that lets you handle common development and operations tasks right in your browser — no install, no sign-up. It offers about 60 tools and practical guides across four areas: network, security, coding, and text.
What we build
We built a single place to handle the tasks developers, operators, and marketers run into repeatedly — IP/DNS diagnostics, generating passwords, hashes, and tokens, formatting JSON, SQL, and HTML, and searching, replacing, and converting text. Instead of hopping between scattered sites, you can find the tool you need by category and use it immediately.
Our principles
- Nothing is sent to a server — most tools run entirely in your browser (client-side), so the text and files you enter are never transmitted. The few lookup tools that require a server are spelled out in our Privacy Policy.
- No sign-up — anyone can use every tool without an account or login.
- Verified for accuracy — tools involving algorithms (hashing, encoding, certificate parsing, etc.) were cross-checked against standard implementations (node, openssl, and more) to confirm the results match.
- Paired with concepts — every tool includes how-to steps, examples, and FAQs, alongside guides that explain the background concepts.
Sister sites
Developk's Tools is part of a family of free web utilities run by developk. The sister sites that follow the same principles (no server, no sign-up) — the PDF toolkit FastestPDF, the image toolkit Pixzero, and FastestUnitConverter — are linked at the bottom of this page.
