See what 3Cols offers in 2026: a free cloud code snippet manager with three-column boards, real-time collaboration, and VSCode and browser extensions.
3Cols is a free, cloud-based code snippet manager that helps developers store, organize, and share reusable code snippets. Its name comes from the three-column board layout used to organize snippets, not from any kanban or project management functionality.
Snippets are stored in the cloud and accessible from any device, and boards can be shared privately with individuals or teams for real-time collaborative editing.
The tool is built by independent developer Oli Blade, and public information about the company behind it, such as a founding year or headquarters, is limited, suggesting it is a small or independently run project.
3Cols organizes code into three-column boards with support for roughly 140 programming languages and syntax highlighting.
A browser extension lets users capture code snippets directly from web pages, while an official VSCode extension allows inserting, updating, and creating 3Cols snippets from inside the code editor.
The web app is built as a Progressive Web App, so it can be installed as a standalone application on Windows and Android in addition to running in a browser.
3Cols is completely free, with no cost to store, access, or share snippets.
No paid tier or premium plan is publicly advertised on the platform.
This makes it accessible to individual developers or small teams without any billing commitment.
