Refact.ai

Refact.ai is an AI coding assistant you can host yourself. It offers code completion, refactoring and an agent mode, and it is one of the few assistants that ships a deployable server rather than only a cloud service.

What is Refact.ai?

Refact.ai is a development tool from a team that has been building code models since 2022. Its selling point is control: you can run the model on your own hardware so source code never leaves your network. It works as a VS Code and JetBrains plugin backed by either the hosted service or your own GPU box.

Product Features

• Self-hosting: a Docker image runs the server on your own machine or VPC.
• Code completion: inline suggestions tuned for fill-in-the-middle across many languages.
• Agent mode: plans and applies multi-step changes in the IDE.
• Refactoring tools: renames, extracts and simplifies selected code.
• Local fine-tuning: adapts the model to your private codebase.

Product Highlights

Self-hosting is not marketing here — you really can disconnect the plugin from the internet. For teams with strict data rules, that removes the legal dance of sending code to a third party.

The price for that freedom is hardware. A usable local setup wants roughly 16GB of VRAM, and quality trails the biggest cloud models. If your GPU is modest, completions get noticeably weaker.

Use Cases

• Regulated teams that cannot send code to external servers.
• On-prem development on air-gapped machines.
• Fine-tuning a model on a private internal codebase.
• Cutting per-seat AI costs by running one shared GPU.
• Prototyping completions for an uncommon language.

Is Refact.ai free?

There is a free cloud tier with limited completions. Self-hosting is free to run on your own hardware, and commercial support plans are sold separately for teams that need SLAs.

Quick Summary

• Refact.ai is built around self-hosting and privacy.
• Needs about 16GB VRAM for a good local experience.
• Supports VS Code and JetBrains.
• Local model quality lags top cloud models.
