Elixium Coder
AI coding that lives in your IDE and can run fully offline.
Practitioner-led transformation
We work with your teams to change delivery habits, platform foundations, and decision quality so capability remains after we step back.
What It Is
Elixium Coder is a source-available coding agent for Visual Studio Code, built and maintained by IndirectTek. It runs locally against models served by Ollama, LM Studio, or vLLM, and connects to Anthropic, OpenAI, or AWS Bedrock when hosted models are preferred. There is no account, no cloud sign-in, and no telemetry — outbound traffic is restricted to the LLM endpoints and MCP servers you explicitly configure.
Why It Exists
The teams we work with — government, regulated industry, and IP-sensitive product groups — cannot send their source code to a third-party SaaS just to get useful AI assistance. As Roo Code shifted toward cloud-first delivery, our customers needed a path that stayed compatible with their existing workspace rules and configuration but kept the entire data plane under their control. Elixium Coder is that path: a single-vendor, Apache-2.0 licensed extension with a supply chain you can audit and a network posture you can defend in a security review.
Capabilities
- Six agent modes: Architect, Code, Ask, Debug, Orchestrator, and Designer — each tuned for a distinct point in the development loop.
- Local-first model support: First-class integration with Ollama, LM Studio, and vLLM, plus any OpenAI-compatible endpoint.
- Hosted providers when needed: Anthropic, OpenAI, and AWS Bedrock as opt-in alternatives.
- MCP integration: Configure Model Context Protocol

.elixium/mcp.jsonto extend the agent with project-specific tools. - Air-gapped ready: Credentials stored in VS Code secret storage; outbound traffic limited to endpoints you configure.
- Roo Code migration path: Compatible workspace rules and configuration formats so existing teams can move without rewriting their setup.
How We Use It
Elixium Coder is the IDE-side companion to the broader Elixium.ai delivery workflow. On client engagements where source cannot leave the network, we deploy Elixium Coder pointed at a customer-hosted model, wire in MCP servers for their internal tools, and use the same agent modes our team runs against cloud models — without changing how the work gets done.
