Still Searching for a Replit Alternative? What Your CS Classroom Actually Needs

When your classroom tool disappears

In November 2023, a lot of computer science teachers opened their inbox to bad news. Replit was shutting down Teams for Education, the classroom version many of them had built entire courses around. As The Register reported, teachers around the world were left scrambling, and Replit's CEO said the product "was losing a ton of money for the business." The service officially ended on August 1, 2024.

Three years on, people are still searching for a Replit alternative. Some picked a quick replacement that never quite fit. Others are now planning a bigger change for their department. If that's you, this post is a simple checklist of what a classroom coding tool really needs to do, so you only have to switch once.

What made the classroom version so popular? According to The Register, it let students code together in real time, a bit like Google Docs, and it automated code checks so teachers could assess work faster. Losing it meant rebuilding assignments, test cases, and grading routines from scratch.

First things first: pick a tool built for teaching

Replit's own explanation was simple: the education product was losing money. When a classroom product isn't central to a company's business, it's always at risk.

So before you compare features, ask a simple question: is teaching programming what this company actually does? Look at who their customers are, what their roadmap talks about, and whether their pricing is designed for schools and universities. It's also worth checking whether you can export your assignments, test cases, and student work in a format you can reuse.

The checklist: what your classroom needs

Coding in the browser, with nothing to install.

Installing compilers on 60 different laptops can eat the first week or two of every term. Students on Chromebooks, older laptops, or shared lab machines get left behind. A browser-based environment means everyone starts coding on day one.

The same setup for every student.

"It works on my machine" is the oldest excuse in programming. When every student gets an identical, preconfigured environment, you spend your time teaching code instead of fixing setups.

Support for the languages you teach.

Python today, Java next term, and C for systems programming. You don't want a different tool for every course in the department.

Assignments and grading in the same place.

Teams for Education was popular partly because it combined coding with assignment management and automatic checks. Make sure your replacement does too, ideally with feedback students can act on before the deadline.

Integrity features for real assessments.

Labs are one thing. Midterms are another. If you run coding exams, you need a way to verify identity and monitor the session, especially now that ChatGPT can write most intro-level answers.

A fit with your existing systems.

Your university already uses an LMS. Your new tool should work alongside it, not make students log into yet another disconnected site.

Room to grow.

A tool that works for one class of 30 should also work for a department with 3,000 students, without someone in IT setting up servers.

Questions to ask before you switch

Before you commit, ask any vendor:

• What happens to my course content if I leave?
• Is this product your main business or a side offering?
• Can I try it with one real class before the whole department moves?
• How do you handle grading, feedback, and academic integrity?

Their answers will tell you a lot. If a vendor can't answer the first one clearly, keep looking.

How Lab.Computer checks the boxes

We built Lab.Computer for exactly one job: helping universities teach programming. Students code directly in the browser, with no installation and support for more than 40 languages. Each assignment launches in its own cloud environment, set up for your course, whether you have 30 students or 3,000.

Beyond the coding environment, our AI assistants help you create assignments with test cases and rubrics, evaluate submissions with detailed feedback you review before it's released, and run secure assessments through our built-in ProctorTrack integration. It also fits alongside your existing LMS.

Switching tools is never fun. But if you're doing it anyway, it's a good chance to pick something that saves you time every week instead of just replacing what you lost.

Quick takeaways

• Replit's classroom product closed in 2024, and many schools are still looking for a long-term replacement.
• Pick a tool built for teaching, with browser coding, grading, and integrity in one place.
• Test it with one real class before switching the whole department.
