Collaborative code editor: how to choose one
A collaborative code editor lets several people write the same code at the same time and see each other's edits instantly. This page explains what it is for and compares seven tools using facts from their own websites. CodeShare is one of them, and it is our product, so we say plainly where it does not fit.
Free, no sign-upWhat a collaborative code editor is
In a regular editor only its author sees the code. To show it to someone you send a file, a repository link or share your screen. In a collaborative code editor everyone opens one link and works in one file: each person sees the others' cursors and edits in real time, as in Google Docs.
There are two kinds of collaborative editors. The first is an IDE extension: everyone stays in their own editor and the host shares a project. The second is a browser service: nothing to install, a link is enough. The second is easier when the other person does not have your setup, such as a candidate in an interview or a student.
The key difference between tools is code execution. Some editors only highlight syntax. Others run the code on a server and show the output to everyone. Interviews and lessons almost always need execution: code you cannot run has to be discussed in words.
What a collaborative code editor is used for
Technical interviews
The interviewer sends a link, the candidate solves a task while the interviewer watches, and both run the code. The candidate should not need to sign up or install anything, and the interviewer needs tasks, notes and scoring.
Pair programming
Two developers write one function or fix one bug. For a whole project an IDE extension is more convenient; for one file or task a browser service is enough.
Lessons and tutoring
A teacher and a student write code in one window: the teacher sees where the student goes wrong and helps right away. This needs a simple link and execution in the course language.
Code review and walkthroughs
People go through a piece of code together: edit it, run it, compare versions. A link-based session suits a short walkthrough; reviewing a whole branch belongs in your Git host.
Collaborative code editors compared
We took the tools that show up most often in roundups of collaborative coding and interview tools. The data comes only from their official websites, with the date we checked. Where a tool does not say something, we write that.

How to choose a collaborative code editor
- For interviews, pick a tool where candidates do not sign up and code runs. If you need a built-in call and a large question library, look at the paid interview platforms.
- For pair programming on a project in your own IDE, VS Code Live Share fits: the host shares the project and the guest joins by link.
- For prototyping a web app with a live preview, cloud IDEs such as Replit are convenient.
- For a lesson, a task walkthrough or a quick check of some code on one screen, a browser-based collaborative code editor that opens from a link and runs code right away is enough.
Where CodeShare does not fit
- CodeShare has no video call: run the call in Zoom, Google Meet or another service.
- There is no framework preview: you cannot see a React, Vue or HTML page rendered as a site.
- A session holds up to 5 people, so it does not suit streaming to a large audience.
- It is not an IDE for a whole project: project files, dependencies and Git stay in your own editor.
A collaborative code editor for your language
Each language has its own page: a sample, the version, the limits and typical interview tasks.
Frequently asked questions
- Is there a free collaborative code editor?
- Yes. CodeShare is free: you create a session with one click, people join by link, and code runs in 11 languages. Some other tools in the table have free plans too, with limits such as on saved documents or collaborators.
- Do you need an account to write code together?
- Not in CodeShare. You can start a session without signing up, and guests never need an account. A free account adds your own tasks, interview mode, scores, notes and interview history.
- How many people can edit code at the same time?
- A CodeShare session holds up to 5 people. Everyone sees the others' edits and cursors in real time.
- How is a collaborative code editor different from screen sharing?
- With screen sharing one person types and the others watch. In a collaborative code editor everyone can type and run code, and nobody waits to be handed control.
- Can you run code in a collaborative editor?
- It depends on the tool: the table has a column for it. In CodeShare code runs in an isolated sandbox on the server, and everyone sees the output.
