But as your projects grow in complexity or you need more flexibility, performance, or integration with tools like CI/CD and automated testing, you might find yourself exploring Replit alternatives.
In this blog, we'll explore eight Replit alternatives that cater to different use cases—from real-time collaboration to serious backend dev. We’ll also show you how integrating a testing automation tool like Keploy can drastically improve your workflow, especially if you're working on APIs or microservices.
Why Look for Replit Alternatives?
While Replit is excellent for fast development and educational purposes, developers and teams may need:
- More storage, processing power, or language support
- Integration with Git workflows or CI/CD pipelines
- A better local-like coding experience in the browser
- Built-in support for frameworks and testing tools
- Enhanced privacy and security for sensitive projects
That’s where these Replit alternatives shine.
- Gitpod
Gitpod is a cloud-based IDE designed for professional developers. It spins up ready-to-code environments from your Git repositories. Gitpod offers native support for Docker, GitHub, and VS Code.
Best for: Teams that use Git workflows and want automated dev environments
Pro Tip: Pair it with Keploy to record real API traffic and generate tests while you develop!
- CodeSandbox
Popular among frontend devs, CodeSandbox supports React, Vue, and Next.js projects with a seamless dev experience. It also enables real-time collaboration.
Best for: Rapid UI prototyping and frontend experiments
Bonus: You can mock APIs directly—then plug Keploy in later to test the real endpoints.
- Glitch
Glitch is known for its creative, community-first vibe. It’s ideal for quick full-stack projects and sharing ideas. Its remix feature lets you clone and modify apps instantly.
Best for: Creative coders and quick prototyping
Limitation: Not suited for enterprise-level backend development
- Coder
Coder transforms VS Code into a cloud IDE, hosted on your infrastructure. It’s designed for teams that need performance, security, and remote access to dev environments.
Best for: Enterprise and secure, self-hosted coding
Pro Tip: Integrate Keploy into your pipeline to automate API tests from day one.
- StackBlitz
StackBlitz runs in the browser and compiles your code using WebContainers. It offers lightning-fast performance, especially for frontend frameworks.
Best for: Frontend development with near-instant startup times
Drawback: Limited backend support compared to full-stack platforms
- Theia
Theia is an open-source IDE framework backed by Eclipse. It’s customizable and used in many commercial cloud IDEs.
Best for: Teams building their own cloud IDE solution
Bonus: Can be integrated with external dev tools and test frameworks like Keploy.
- AWS Cloud9
AWS Cloud9 is Amazon’s official cloud IDE, deeply integrated with AWS services. It allows real-time collaboration, access to EC2 instances, and a full terminal experience.
Best for: DevOps, serverless development, and AWS-native workflows
Pairing Tip: Use Keploy to test your Lambda APIs or EC2-hosted apps with ease.
- PaizaCloud IDE
This lightweight IDE supports multiple languages (Python, Ruby, Node.js, etc.) and spins up environments quickly—great for learning or small projects.
Best for: Educational or lightweight development
Drawback: Limited customization and enterprise support
Supercharge These IDEs with Keploy
Choosing a great Replit alternative gets you halfway there—but if you're working with backend APIs, microservices, or full-stack apps, you’ll also need effective testing. That’s where Keploy comes in.
What is Keploy?
Keploy is an open-source testing tool that records real API traffic (requests and responses) and automatically generates:
- Unit tests
- Integration tests
- Mocks
All of this is done without writing a single line of test code.
How Keploy Complements Cloud IDEs
- Record API calls from your dev environment in Gitpod, Cloud9, or Glitch
- Auto-generate test cases and mocks
- Replay them during CI/CD to prevent regressions
- Works with any language or framework—Node.js, Go, Python, Java, and more
By combining a cloud IDE with Keploy, you don’t just write code faster—you test smarter too.
Final Thoughts
Whether you’re building APIs, coding frontends, or managing full-stack projects, there’s no shortage of excellent Replit alternatives. Each cloud IDE offers its own strengths, from deep integrations with Git to powerful live collaboration.
But speed alone isn’t enough—quality matters too. Integrating Keploy into your development environment ensures you're building with confidence, catching bugs early, and maintaining reliable APIs without writing manual test scripts.
So go ahead, try out one of these Replit alternatives—and while you’re at it, plug in Keploy to level up your testing game.
