CodeSee enables thousands of developers to visually map and understand their code.

“I like the ability to apply Labels and Notes to a CodeSee Map. The Notes are really, really helpful.”

Joan M. Davis

“I am able to visually see the changes in a pull request and begin to create a phased solution for staggering deployments. CodeSee now provides my primary method to identify differences in the code and where to make changes.”

Amy Meyers

Pvolve

“I really like everything being visualized, which is why I use CodeSee.”

Jack Gaarkeuken

Full-stack Developer

“Using CodeSee to take on a new codebase, I’m able to save up to 4 hours a week across my open-source projects.”

Joan M. Davis

"This is legitimately cool. Don't miss out."

Kyle R. Conway

“CodeSee allows Distribute Aid to implement relay-style code handoffs. Maps document the current state of the code for incoming devs, so others can wind down. Everyone is up to date, and we can maintain our momentum without burning out our volunteers.”

Taylor

Senior Engineer, Distribute Aid

"A pretty interesting product for understanding large codebases logically instead of going through plain text documentation."

Akash Hamirwasia

@blenderskool

“Quickly and scalably onboard engineers by visualizing your codebase. Code as stories, document as you go. Plenty to like, one to watch for 2021.”

James Governor

Co-Founder, RedMonk

"Been using CodeSee and it's a game changer... get used to navigating a codebase fast."

Lucia Cerchie

@CerchieLucia

"... I am very excited for how much easier navigating code reviews will be."

“CodeSee gives me more visibility into what code is responsible for what parts of the product. So if I’m interacting with a given product/given project, and I need visibility into what parts of the code are responsible for doing what I am doing at a particular time, CodeSee really helps with that.”

Try CodeSee for a maintainable, resilient codebase.

Bugs, fires, security breaches, missed deadlines, & spaghetti code all stem from engineers not understanding 99% of the code. Visually summarize your code at the most critical parts of your workflow, including onboarding, planning, & code reviews.

Maps provide a reliable visual foundation for building codebase understanding, so developers can start making meaningful contributions without the friction often associated with onboarding.

Dependencies that connect code files in a Map.

See the impact of your changes, elevate unknowns, automate your codebase, process insights and walk someone through how to complete your review. With CodeSee, detect if the change was real or just moved code — and complete your review in logical chucks instead of alphabetically.

Learn more

Code files connecting to dependencies within a folder in a Map.

Once your codebase is mapped, we provide visual tools to connect any code knowledge directly to the code. As your code changes, your knowledge persists. Connect feature boundaries, tech debt, team ownership, gotchas, critical paths through the code, and more.

Sharing development details is key to cross-organization project management, but code is not a universal language. Maps can be used to guide collaboration and communication, no matter an individuals code knowledge.

How Maps works.

Quickly and reliably understand how files are related, see how code changes fit into the larger software architecture, and more.

Maps are automatically generated and sync to your codebase with each commit, so you never have to worry about manually updating your Map.

Use Insights to visualize the most active areas of a codebase and get details on individual files, including file age and how many lines of code they represent.

Code files and dependencies labeled with notes in a CodeSee Map

Maps displays files and folders for any language, with the ability to visualize dependencies in Go, Java, JavaScript, Python, and TypeScript.

The different code languages displayed in CodeSee Maps

Customize Maps and provide context to your code using Labels and Notes, with color coding to indicate feature bounds, mark hotspots, or highlight tech debt—whatever’s useful to you.

Code files and dependencies of a CodeSee Map

Create visual walkthroughs of your code, using Tours to communicate ideal code paths, user flows, and more—and Tour Alerts will help you keep your Tours up to date.
