CodeSee is a code visibility platform that helps developers understand and navigate codebases more efficiently. It offers features such as codebase onboarding and offboarding, refactoring support, auto documentation, debugging assistance, QA test plan creation, and standardization of dev processes. With CodeSee, developers can gain visibility into their code, understand dependencies, and collaborate effectively. The platform is designed for dev teams of all sizes and provides real-time insights and automated code knowledge. CodeSee has been praised by various users for its ability to improve code understanding, code reviews, and onboarding processes.
CodeSee
Devs spend 60% of their time reading and understanding code because they don't have a smart way to consume mental models of their code, services and dependencies.
Codebase Onboarding
Codebase onboarding doesn't just happen when hiring. It happens when you need to understand how your code works, devs left, up/down stream dependencies, outages, reorgs and more.
Codebase Offboarding
Whether because of a restructure or a RIF, we're all feeling the effects of needing to work in the codebase without the devs who wrote it. Let CodeSee make it easier on the team.
Refactoring
Knowing how all the pieces in a system fit together influences the ability to move quickly when breaking down modules, breaking up monoliths into services or changing legacy code. CodeSee shows all the file dependencies in your codebase.
Auto Documentation
Developers hate writing documentation so get real time understanding and observability that you can rely on.
Debugging
When trying to debug a challenging problem, F12 isn't enough. Understanding your code flow and function impact is.
Make QA Test Plans
Help your QA teams know what to test and the impact a code change has.
Standardize & secure dev processes
Too much autonomy can result in sprawl, knowledge silos and runaway costs. Create standards to deliver reduced complexity, enforce stronger security, and compliance.
Understand every service, dependency, database, api, repo, function, and their impact.
Be confident with your code decisions. Code maps give devs confidence by minimizing lack of insight into dependencies and maintaining control as your code base grows.
Deliver secure software faster
Understand application complexities
Uncover unknown unknowns in mins
Follow function level logic in your editor
Tease out the impact of a function and figure out how something convoluted works.
Understand repo level code dependencies.
Create views on top of your code to articulate features, tech debt, ownership, etc to avoid pitfalls or gotchas that persist.
Flows image
Auto generated and auto updated.
Auto generate and auto update your map as your code changes. No additional work required.
Flows image
Map your code.
Get instant mental models of your code for rapid understanding so your team can get back to shipping code.
Map your code

"CodeSee's automated cross-repo visualization tools allow our development teams to see inside each other's codebases. Our devs use CodeSee's holistic view of our system to more easily understand their codebase and to communicate the complexity of their work to other people around the business."
Chris Poel
Head of Engineering, River Island

"... 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.”
Ryan Abrams
Senior Engineer, Stripe
“I like the ability to apply Labels and Notes to a CodeSee Map. The Notes are really, really helpful.”
“I am able to visually see the changes in a pull request and begin to create a phased solution for staggering deployments."
