Find the right API and developer utility to save time on everyday development work. This page lists tools for working with APIs, testing endpoints, formatting data, generating SQL and regex, converting code and handling the many small tasks developers do every day. Every tool is reviewed by a real person before it goes live, so you can compare options with confidence.
These are focused tools that solve one developer problem well. Instead of a full coding assistant, they do a specific job: test an API call, turn a sentence into an SQL query, check a regular expression, format messy JSON or generate a config file. Many work in the browser with no setup, and some offer an API so you can build them into your own apps.
API and dev utilities suit backend and frontend developers, data engineers, QA testers, technical founders and students. If you want to spend less time on small, repetitive tasks, you will find useful tools here.
Start with the task that slows you down most. Then check whether the tool works in the browser or through an API, how accurate its results are, the pricing and the free plan. Be careful with what you paste in. Do not share secret keys, passwords or private customer data with any online tool unless you have checked its privacy rules. Open each listing to see features, use cases and pricing details before you decide.
We check every listing by hand and keep the information up to date, so you can trust what you read. Browse the API and dev utilities above, compare them and pick the one that fits your stack.
