Code, learn, and finish your labs.

Name: LabBench
Author: Susanta Banik

LabBench is a practical coding workspace for students. Write programs, run them, understand errors, organize your files, and prepare clear output for lab records—all in one place.

Why LabBench exists

Lab classes can be interrupted by locked-down computers, missing software, files left behind on a shared machine, and the hassle of moving screenshots into a report. When something goes wrong, students also need an explanation that helps them learn—not just a replacement answer.

LabBench brings the everyday parts of a programming practical together: a place to write and run code, inspect results, get a useful debugging hint, and keep submission material organized. You can begin working without creating an account; Google Drive is available when you want your workspace backed up to your own account.

What you can do with LabBench

The tools are designed around the full practical workflow, from opening a blank file to sharing or submitting your results.

Start coding without setup

Open a language workspace when you need it. LabBench gives you a clean, blank file so you can write and organize your own work, then saves it in your browser as you go. No account is needed for the core workspace.

Keep projects organized

Create files and nested folders, then rename or remove them as your lab work changes. Add languages from the workspace when you need them.

Write, run, and preview

Edit with language-aware highlighting, format code, run supported programs, enter input in the terminal, and see web projects in a live preview. Language support and execution methods vary by language.

Understand errors with hints

Ask the AI Teaching Assistant to explain code and recent output in plain language. It is designed to guide your debugging rather than hand over a finished solution. Five free hints are available each day, with an optional Pro Pass for unlimited AI hints.

Prepare clear lab submissions

Capture terminal or preview output as an image. Save Ink switches to a high-contrast light appearance for printing and reports.

Continue on another device

Share a workspace with a QR code or temporary link that lasts 24 hours. Recipients can review the files and output, then download them together as a ZIP.

Keep a Google Drive copy

Sign in with Google to sync your workspace to your own My Drive/LabBench folder and upload code and output captures. Drive access is optional.

Learn the workspace quickly

Use the guided product tour to find the main tools, and install LabBench from a supported browser if you want a convenient app-like shortcut.

Languages for different lab courses

Start with HTML, CSS, JavaScript, React, Python, Node.js, C, C++, Java, C#, PHP, or Go. You can also add Bash, Rust, Ruby, TypeScript, Scala, Swift, SQL, R, Haskell, Lua, Perl, Pascal, Julia, D, Elixir, and Zig. How a program runs depends on the language; web projects can be previewed, while other supported languages run in their available environments.

Built by a student-minded maker

LabBench was created by Susanta Banik to make common programming-lab work less fragmented and more approachable. The aim is practical: make it easier to practice, understand, and present your own work.

Made for learning, with clear limits

LabBench is a working learning tool, not a promise of perfect answers or uninterrupted service. The AI assistant offers explanations and hints, and students remain responsible for writing, checking, and understanding their programs. Core editing is available without sign-in; AI help, online execution, and connected services depend on availability and their own usage limits.
