What is Caildus? An AI development companion that writes, reviews and refactors code

Caildus is an AI-powered development companion for building intelligent, scalable web applications. It works alongside developers to write, review and refactor code: you connect a GitHub repository, an AI agent analyzes the codebase, and its suggestions arrive as visual diffs you can review and apply with a single click. Caildus is built by OXS Corp, the technology company founded by Batuhan Emre TAMAM, and is available at caildus.com.

The short version

Caildus takes on the repetitive parts of software work — boilerplate, refactoring, routine reviews — so developers can spend their time on architecture and ideas. It is repository-aware, it proposes rather than imposes, and its agents can be extended with tools through the Model Context Protocol (MCP).

How Caildus works

Caildus describes its workflow in a few steps.

1. Connect a repository. Sign in with GitHub or clone any repository. The agent is activated with no configuration.
2. Let the agent read the codebase. It analyzes the project and starts suggesting improvements, using context from the whole codebase rather than a single file.
3. Ask in plain English. Request a feature, a review or a bug fix the way you would describe it to a colleague.
4. Review the diff, then apply it. Every change comes back as a visual diff. Nothing is applied until you choose to apply it — with one click when you're happy.

What Caildus can do

Write and refactor code

The agent writes boilerplate, builds features from plain-language requests and refactors legacy code. Caildus also describes writing tests and reviewing every commit as part of its role, so problems are caught before deployment rather than after.

Review, built into the workflow

Review isn't an afterthought in Caildus — it's the interface. Proposed changes are shown as diffs alongside the existing code, so a developer always sees exactly what will change. That keeps a human in the loop for every edit that reaches the codebase.

Extend agents with MCP

The Model Context Protocol (MCP) is an open standard, introduced by Anthropic in November 2024, for connecting AI models to external tools and data sources. Caildus lets you search for and install MCP servers with one click, extending an agent with design tools, frameworks, databases and APIs so it can work with the rest of your toolchain.

Run agents in parallel

Larger tasks can be split across several agents working in parallel, each with its own role. Caildus shows token usage and progress as each agent completes its steps, so parallel work stays visible.

Build and ship websites

Caildus also works as an AI website builder. You can chat with the AI to generate a full website from scratch, start from a pre-built design, or upload a screenshot and have it recreated in code. Elements can then be edited visually — click to change colors, fonts and spacing — and the finished site can be deployed to a custom domain or exported to GitHub.

Who Caildus is for

Caildus is made for developers and engineering teams who want an AI partner that understands their codebase, and for founders and non-developers who want to build and ship a website by describing it. You can start for free with daily credits and no credit card; current plans are listed on caildus.com.

Caildus inside the OXS ecosystem

Caildus is part of the OXS ecosystem, presented under the name OXS Holdings, and its website credits OXS Corp: the footer reads "© 2026 Caildus · OXS Corp." It operates as an independent brand with its own product, plans and community.

Caildus is also at work elsewhere in the ecosystem. The website of Kointage — OXS Corp's AI platform for financial research — carries a "Powered by Caildus" credit. For more on the company behind both, read What is OXS Corp?

Why Caildus is built this way

Two choices define Caildus. The first is that it reads the whole codebase before it suggests anything, because useful code depends on context. The second is that it proposes changes rather than making them silently, because developers are responsible for what ships. Both follow the same principle that runs through every OXS company: technology should make people more capable without taking decisions away from them. The principles are set out on the philosophy page.

Frequently asked questions

What is Caildus?

Caildus is an AI-powered development companion that writes, reviews and refactors code. It connects to GitHub repositories, proposes changes as reviewable diffs and can be extended with MCP integrations.

Who makes Caildus?

Caildus is built by OXS Corp, a US technology company founded by Batuhan Emre TAMAM.

Is Caildus free?

Caildus offers a free start with daily credits and no credit card required. Paid plans add more capacity; see caildus.com for current details.

Does Caildus change my code automatically?

No. Caildus proposes changes as visual diffs, and they are applied only when you choose to apply them.

What is MCP in Caildus?

MCP, the Model Context Protocol, is an open standard for connecting AI models to tools and data. Caildus uses MCP servers to extend its agents with design tools, frameworks, databases and APIs.

Can Caildus build a website?

Yes. Caildus can generate a website from a chat description, a template or a screenshot, let you edit it visually, and deploy it to a custom domain or export it to GitHub.
