Build with HTML, CSS and JavaScript
Create your app with CodVerter’s web editor or with your preferred development tools. When the app is ready, you can save it, test it and prepare it for public review.
For developers
A place for practical web apps
CodVerter Web Apps is focused on small, useful browser-based applications: calculators, educational tools, productivity utilities, games, visual demos and other apps that people can open and use immediately. The goal is quality, usefulness and discoverability.
Submit for review
Public apps are reviewed before they appear in the directory. We check usability, visual quality, stability, performance and safety so users can explore the collection with more confidence.
Publish to the directory
Approved apps receive a public page with title, description, image, author information and live preview. This makes your work easier to share and easier for users to discover.
Keep improving your app
Publishing is not the end of the process. You can continue improving the app, refining the experience and building more useful tools over time.
Start building
Open the CodVerter editor and create your next app.
Build a practical tool, a calculator, a small game, a visual demo or anything useful that can run in the browser.
Review guidelines
What we look for before publishing
These guidelines help keep CodVerter Web Apps useful, safe and pleasant for visitors. They are not meant to limit creativity. They are here to protect the quality of the public directory.
UI and responsive behavior
The app should work properly on desktop, tablet and mobile where possible. Layout changes are fine, but the core functionality should remain usable.
Visual quality
Text, images, controls and layout should look clean and intentional. Avoid crowded screens, broken spacing, blurry graphics and unreadable text.
Accessibility and usability
Buttons and interactive areas should be easy to use with a mouse or touch. Text should have enough contrast, and the app should be understandable without hidden instructions.
Stability
The app must not freeze the browser, crash repeatedly, trap the user, create infinite loops or behave aggressively.
Performance
The app should load quickly and respond in a reasonable time. If something takes longer, show clear feedback such as a loading indicator or progress message.
Content and safety
Apps may be rejected or removed if they contain unsafe, misleading, abusive, deceptive or inappropriate content.
- No phishing, scams, credential collection or impersonation.
- No malicious scripts, forced redirects or abusive popups.
- No inappropriate, hateful, sexual, violent or abusive content.
- The title, description and app purpose must be clear.
