Overview

Kilo Code is an open-source AI coding assistant designed to work with various integrated development environments (IDEs) such as VS Code and JetBrains. It is built to plan, write, and debug code, offering support for multiple models. This tool aims to provide developers with a flexible and cost-effective solution for AI-assisted coding, allowing them to choose from over 500 models without markup, including the option to use their own model keys. Kilo Code operates under an open-source license, ensuring transparency and the ability for developers to inspect, modify, and self-host the software if needed. One of the key features of Kilo Code is its ability to work across different platforms and environments, including local machines, cloud services, and even within Slack for team collaboration. It supports various modes of operation, such as Code Mode for writing and refactoring code, Architect Mode for planning complex features, and Debug Mode for identifying and fixing bugs. Additionally, Kilo Code introduces Auto Model, a feature that automatically selects the most appropriate model based on the task at hand and the user's budget, eliminating the need for manual model selection. Kilo Code is designed with the philosophy that AI coding tools should work for the developer, not against them. It emphasizes flexibility, transparency, and cost-effectiveness, making it an attractive option for individual developers and teams looking for an open-source solution that can integrate well with their existing workflows. The tool's open-source nature also means that it can be audited, modified, and extended by the community, potentially leading to a richer set of features and models over time. The flexibility of Kilo Code extends to its pricing model, which is designed to be aligned with the costs of the models used, without any additional markup. This approach, combined with the support for local models and the ability to bring your own keys, aims to provide a cost-effective solution for developers. Furthermore, the tool's support for parallel isolated worktrees and IDE and CLI sessions enhances its usability in different development environments. In terms of comparisons with other AI coding assistants, Kilo Code's open-source approach and transparent pricing model set it apart. While other tools may offer similar functionality, Kilo Code's commitment to openness and community involvement could make it a more appealing choice for developers who value these aspects. However, the effectiveness of Kilo Code ultimately depends on the quality of its models and the user experience, areas where continuous development and community feedback are crucial. Overall, Kilo Code presents itself as a versatile and developer-friendly AI coding assistant, designed to adapt to various workflows and preferences. Its open-source nature, flexible pricing, and commitment to transparency are key selling points for developers looking for a customizable and cost-effective AI coding solution.

Solid for our team

We rolled this out across the team last quarter and the value for money is strong. The integrations fits neatly into how we already work, and the integrations removed a step we used to do by hand. Pricing gets steep at scale, which is the main caveat, but it has held up under daily use.

Does the job

Pretty happy overall. The API just works and the value for money is strong. Pricing gets steep at scale can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Years in this space

I've evaluated a lot of these over the years. What stands out here is the integrations — handled better than most — and the value for money is strong. Worth the time if this is your use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the automation, and it is genuinely easy to set up caught me off guard. A few rough edges remain is why this isn't a perfect score, still, I'd recommend giving it a real trial.
