Coderpad Alternatives: The Best Free Live Coding Interview Tool in 2024

By Wes Winham

Updated for 2024: VS Code Live Share still the best free live coding interview tool (AKA free coderpad)

Live coding interviews show you how a candidate works with others and communicates their ideas. But until recently you were stuck either using an inferior tool like Google Docs, or paying up for a dedicated technical interview tool like coderpad when you really just need a shared IDE.

This guide shares why VS Code Live Share is the best free coderpad option for most and how to use it to run your live coding interviews.

Enter: VS Code Live Share The Best (Free) Live Coding Option

VS Code now has built-in pair programming support! Using this plugin for your live coding interview has major advantages over every alternative:

  1. Familiarity: VS Code is already the single most widely-used IDE, so most engineers are familiar with it
  2. Bring Your Own Config: Candidates can use their already-configured IDE with their settings
  3. Great Plugin Support: VS Code has a wide range of plugins that candidates will already be familiar with. Need VIM mode? VS Code has you covered
  4. Browser-based Option: For candidates without VS Code installed, they can load it up from the browser with zero install required.
  5. Measure AI Proficiency: (Optional) With AI Proficiency as a productivity multiplier, this is the only live coding interview tool option where you can allow candidates to use AI Programming Assistants like Github Copilot or even new VS Code-compatible AI-first editors like Cursor. Even the paid tools don’t support this!
  6. Free: Alternatives like CoderPad and HackerRank charge a monthly or annual subscription that limit the number of sessions you can run.

With Live Share, you can see your candidate’s cursor and follow their actions.

Here’s how to add this online coding interview tool to your arsenal.

Step 3. Sign in with GitHub or Microsoft (anonymous will work as long as you don’t need to use advanced functions like a shared terminal)

That’s it! Your candidate can now pair program with you.

Not-as-good Alternatives: Language-specific IDEs like PyCharm

In 2023, other language-specific IDEs are beginning to add built-in options for remote pair programming. PyCharm includes the Code With Me plugin as part of a license.

The major downside is that none of these options have the browser-based option like VS Code. That means you’ll be reliant on the interviewer installing an IDE locally before your interview.


Hiring software engineers isn’t easy. There’s a lot of competition and it can be tough to find the right candidate.

By incorporating pair programming into your coding interviews, you can screen for both hard AND soft skills while watching how a candidate works in real time. VSCode Live Share is free to use, easy to set up, and adds an extra layer of insight to your interview process.
