Your code is constantly evolving. To deliver resilient code, engineers need visual observability throughout all of their workflow that’s permanent, correct, and current.

CodeSee visualizes your PRs making reviews manageable, increasing the quality of feedback while decreasing the likelihood of shipping bugs.

Reviewers know what issues to look for, what has changed and why, and can visually grasp the impact of every PR, starting with the areas of code with the greatest impact, stepping through code logically instead of alphabetically, and focusing on what’s important.

Auto generate a map of your code.
Map your codebase so that you fully understand how the code works. Once you do, you can understand how every PR affects the rest of your codebase.
Gauge the impact of a change before merging.
See all the parts of code affected by each PR. Break large reviews into manageable pieces directing reviewers to files that have been actually changed.
Automate code for maintainability at scale.
Automate code knowledge, compliance and security processes so your reviews are consistent and engineers know what issues to look for. Well-defined checklists ensure nothing is missed.
Visually share an author’s intent.
Form an instant mental model of what an author intended. Concentrate on development rather than figuring out how the code works. With integration to VS Code.

“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.”
