Open-source autonomous AI coding agent with self-hosting, IDE integration, in-editor chat, and code completion across 25+ languages and major editors.
Refact.ai is an open-source autonomous AI coding agent that plans, writes, executes, and deploys code end-to-end, combining in-editor chat, accurate inline completion, and a full agent workflow into one developer tool. It claims the top spot among open-source agents on SWE-bench and pairs agentic autonomy with the ability to self-host the whole stack on customer infrastructure.
The platform is built on Qwen2.5-Coder with retrieval-augmented generation over the user's own repository, so completions reflect project-specific types, imports, and naming. Integrations with GitHub, databases, and CI/CD tools let the agent run real workflows (open PRs, run tests, query production databases) with supervised approval inside the IDE.
Key benefits:
- Open-source agent under a permissive licence allows full audit and forking
- Self-hosted deployment keeps source code, prompts, and completions on-premises
- Retrieval-augmented completion adapts to project-specific code style and APIs
- Broad IDE support covers VS Code, all JetBrains IDEs, Visual Studio, Neovim, and Sublime
- Autonomous agent mode executes multi-step plans across repos, CI, and databases
- 25+ languages from Python and TypeScript to Rust, C++, SQL, and YAML
Operated by Small Magellanic Cloud AI Ltd., headquartered in the United Kingdom, Refact.ai offers EU and UK hosting under GDPR, plus full on-premises deployment for teams with strict data sovereignty requirements. Self-hosting removes any external data sharing from the loop entirely.
Ideal for engineering teams, regulated enterprises, and open-source contributors that want a Copilot-class coding agent they can inspect, self-host, and run against private codebases without sending anything to US cloud providers.

AI coding assistant deeply integrated across the JetBrains IDE family with in-editor chat, code completion, test generation, and multi-provider model choice.
JetBrains AI Assistant is a deeply integrated AI coding companion that runs inside every JetBrains IDE (IntelliJ IDEA, PyCharm, WebStorm, GoLand, CLion, Rider, RubyMine, PhpStorm, and more), delivering in-editor chat, inline code completion, automatic test generation, commit message drafting, and refactoring suggestions. It leverages the IDE's own static analysis so completions understand the full project context, not just the nearby text.
Unlike plugin-first competitors, the assistant is built by the makers of the IDE itself, so features like project-aware refactoring, safe code transformations, and JetBrains' award-winning code inspections feed directly into AI prompts. Users can choose between multiple underlying models and plug in local LLMs via Ollama or LM Studio for fully offline work.
Key benefits:
- Native IDE integration gives the AI access to full project context and static analysis
- Multi-model choice with OpenAI, Anthropic, Google, and local Ollama / LM Studio options
- Inline completion and chat work together across every JetBrains IDE seamlessly
- Commit message generation and automatic test writing accelerate day-to-day flow
- Free quota available for personal learning and evaluation
- AI agents automate multi-step refactors and cross-file changes inside the IDE
Developed by JetBrains, headquartered in Prague, Czech Republic, with European R&D presence and data handling aligned with GDPR. Enterprise customers can route requests through JetBrains AI Cloud in Europe or bring their own keys to keep data on approved providers only.
Trusted by millions of JetBrains IDE users worldwide, JetBrains AI Assistant is ideal for professional development teams on JVM, Python, JS/TS, Go, Ruby, PHP, and .NET stacks that want a Copilot-class experience without leaving the IDE they already rely on.
