Project

Local Inference Platform

Project Scope We are building a desktop application for deploying and configuring local inference on local devices (e.g. NVIDIA Spark / DGX Spark), managing model lifecycle (start/stop), and connecting coding agents like Claude Code and Codex to locally hosted models. Currently an internal MVP, on the road to open source.

Tech Stack Kotlin, Compose Desktop (with JetPack Compose roots), kotlinx.coroutines, REST APIs for model deployment management

Agent layer: configuration files in toml/json/yaml, LLM proxy routing from agents to BE

Packaging: native installers — msi (Windows), deb (Linux), dmg (macOS)

Challenges

• ▪Building a desktop control plane for local AI agents that abstracts away the messy parts of running LLMs on heterogeneous hardware — model lifecycle, proxy routing, agent configuration, and OS-specific quirks (path separators, signing, packaging) — while keeping the system extensible enough to evolve toward open source. Visualising model statistics and system load on top of a backend that actually does the deployment.
• ▪Team
• ▪Small, startup-like team on the JetBrains side — no bureaucracy, direct contact with potential users, fast iteration. Code reviews as part of the process.
