qodo (formerly CodiumAI) is a sophisticated AI-powered code integrity platform designed to help developers write better code with fewer bugs.
Introduction
qodo (formerly CodiumAI) is a sophisticated AI-powered code integrity platform designed to help developers write better code with fewer bugs.
Unlike generic code completion tools that focus on speed, qodo focuses on logic and correctness. It analyzes your code to understand its intent and automatically generates comprehensive test suites including unit tests, integration tests, and edge case scenarios.
Its mission is to enable “Code Integrity” by providing developers with the tools to verify their logic as they write it, ensuring that software is not just functional, but robust and reliable from the first commit.

Review
qodo earns an exceptional expert gradefor its unique focus on software quality over quantity. While many AI tools simply autocomplete code, qodo acts as a “second pair of eyes” that proactively looks for logic flaws and missing edge cases.
Its primary strength is the meaningful test generation, which produces executable code that often catches bugs developers hadn’t considered. The recent rebranding to qodo signals an expansion into a broader “AI agent” workflow (Codiumate), which manages the entire dev cycle. While the advanced features require a paid subscription, its ability to increase test coverage while reducing manual drudgery makes it a foundational tool for professional engineering teams.
Features
Automated Test Generation
Analyzes your functions and generates a suite of tests including "happy path," edge cases, and error handling.
Code Explanation
Provides a plain-English breakdown of complex logic, making it easier for team members to understand unfamiliar code.
Code Suggestions
Proactively suggests refactors and fixes to make your code more readable, maintainable, and efficient.
PR-Agent
A specialized tool that lives in your Git provider (GitHub/GitLab) to automatically summarize PRs, suggest improvements, and check for bugs.
Behavior Analysis
Maps out all possible execution paths of a piece of code to ensure the AI understands exactly what the code is doing.
Codiumate (AI Agent)
A comprehensive workspace that helps plan features, write code, and verify it as a unified "agentic" workflow.
Best Suited for
Backend Engineers
Ideal for ensuring that complex API logic and database interactions are thoroughly tested.
QA & Test Engineers
Perfect for rapidly increasing code coverage and generating baseline test suites for legacy systems.
Junior Developers
Useful for learning testing best practices and understanding complex code through AI-generated explanations.
Lead Developers
Excellent for enforcing code quality standards through automated AI-powered PR reviews.
Security-Conscious Teams
A strong tool for identifying potential vulnerabilities and input-handling errors before they hit production.
Large Teams
Great for maintaining consistency in PR documentation and review quality across many developers.
Strengths
Finds subtle logic bugs
Reduces manual testing time by up to 80%
PR-Agent provides objective, instant feedback.
Seamless integration with popular IDEs and Git providers ensures the tool is available where developers already work.
Weakness
Context limits on free plans
May generate “noise” if the AI is too aggressive with suggestions.
Getting started with: step by step guide
The qodo workflow is designed to be a continuous loop of writing, testing, and refining.
Step 1: Installation
The user installs the qodo extension in VS Code or their JetBrains IDE of choice.
Step 2: Analyze Code
The developer clicks the “Generate Tests” or “Explain” button next to a function or class definition.
Step 3: Review Suggestions
qodo presents a list of “Behaviors” it found. The user selects which ones they want to test (e.g., “Empty input,” “Max value”).
Step 4: Generate & Run
The AI generates the test code (e.g., in Jest, Pytest, or Mocha). The user runs the tests locally to verify current behavior.
Step 5: Fix & Refactor
If a test fails or qodo suggests a “Code Improvement,” the developer applies the fix directly in the IDE.
Step 6: PR Review
Before merging, the PR-Agent automatically reviews the pull request, adding a summary and checking for any last-minute logic flaws.
Frequently Asked Questions
Q: Is qodo the same as CodiumAI?
A: Yes. qodo is the new name for CodiumAI. The rebranding reflects their growth into a broader AI-powered developer platform.
Q: Does qodo send my code to their servers?
A: Yes, code is processed in the cloud to generate suggestions. However, they offer Enterprise options for local/on-premise processing for teams with strict privacy requirements.
Q: What programming languages are supported?
A: qodo supports most major languages, including Python, JavaScript, TypeScript, Java, C++, and Go, with new languages being added frequently.
Q: Can it generate tests for my existing (legacy) code?
A: Yes. This is one of its strongest use cases. You can point qodo at an old function and it will generate a baseline test suite to help you understand and refactor it safely.
Q: Does it work with my existing testing framework?
A: Yes, qodo can generate tests for standard frameworks like Pytest, Jest, Mocha, JUnit, and more. You can even tell it which style you prefer.
Q: What is the "PR-Agent"?
A: It is a tool that integrates with GitHub/GitLab to automate the PR review process, providing summaries, identifying bugs, and ensuring code quality before a merge.
Q: How is this different from ChatGPT?
A: While ChatGPT is a general model, qodo has deep codebase context. It “sees” your files and environment, allowing it to generate code that actually runs in your specific project.
Q: Can I use qodo for free?
A: Yes, the Individual plan is free and includes core features like test generation and code explanation for personal use.
Q: Does it help with code security?
A: Yes, qodo identifies potential edge cases and error conditions that could lead to security vulnerabilities if left unhandled.
Q: Can I customize the AI's suggestions?
A: Yes, on the Team and Enterprise plans, you can define Custom Rules and coding standards that the AI will follow when suggesting code or reviewing PRs.
