YC DevTools companies that accelerate development, testing, and debugging


While building software, especially in larger organizations, one of the toughest tasks is maintaining uniformity in communication among all involved along with managing all tasks involved. GitLab is a DevOps platform that helps teams move from planning to executing and delivering all in one software. It supports both small businesses and enterprises and provides resources to get started with DevOps.

ReplIt (In-browser IDE)

It’s said that one does not need computers or devices with high specifications to get started with programming. Setting up code editors might be cumbersome for some people and that is the problem Replit is solving. It allows you to write and run code in 50+ languages without any setup. It started as an in-browser code editor and now assists with hosting, collaborative programming, and its own community to increase one’s network and global reach.

Theneo (API Documentation)

If there is one thing developers don’t prefer doing, it is documenting. The process of creating and maintaining docs with different versions being updated frequently can be tedious. Theneo helps in generating Stripe-like API documentation with a few clicks. This documentation is interactive, gives you the ability to import your API collection, tracks user behavior, and supports Python, Java, Ruby, Go, Node.js, and more.

Raven (API for all notifications)

Notifications have become an integral part of retaining users if used correctly. Managing these notifications especially when one has multiple mediums has known to occupy time and other resources.

Requestly (Debugging tool for frontend devs & QAs)

Testing an application for various scenarios is time-consuming and might lead one to spend time finding the right tool to cover even a single edge case that could break the app. Requestly is a platform made for debugging and testing your web and mobile application with features such as redirect URLs, modify Headers, insert custom scripts, mock server, Android debugger, and more.


Security of a service’s infrastructure is a key component when running software as users trust you with their information. Aptible, inspired by Heroku, developed a Platform-as-a-Service (Paas) where they take care of cloud security and the developer can focus on the product. Highly used in the healthcare industry, they provide fully-managed cloud infrastructure, pass security audits, and more.


Design, like many other things, is an iterative process involving not just a designer but the stakeholders, engineers, product managers, and such. It can be a headache to collaborate on a design file while ensuring all requirements are met along with the aesthetics. Zeplin is a workspace for design that is made with the intention of reducing these headaches by giving designers the ability to define user journeys, cite API endpoints, discuss with other team members, integrate with tools that your organization uses, and a Figma plugin.

RainForest (No-code QA Platform)

Software testing is complex and requires comprehensive knowledge of the software to be performed well. While Quality Assurance teams are meant for this, the product developers and managers could add an edge to the testing as well. Rainforest is a no-code testing platform that supports automated, crowdsourced, browser, and mobile testing. It runs tests in parallel using virtual machines to get faster results with detailed reports as well.

Docker (App store for server configurations)

Common problem developers face is making sure their application runs the same in different environments i.e., different OS, OS versions, hardware, etc, these are compatibility issues that affect the efficiency of the team. Docker solves this using container which ensure that each application can manage its own versions and dependencies within itself and not affect the underlying environment and not be dependent on a particular setup either.
