Overview

Axion IDE is an AI-native code editor built with Avalonia and .NET. It pairs a full coding environment with an autonomous AI agent that plans, executes, and verifies work — locally on your GPU or in the cloud.

The 30-second tour

Area	What it does
Axion AI Assistant	Chat with the agent, queue messages, watch the plan execute
DAG Pipeline	Autonomous sub-agent pipeline — each role runs on the model you assign
Fallback Tiers	Multi-provider failover chain with API keys and live balances
MCP Hub	Connect Model Context Protocol servers — 400+ in the marketplace, plus GitHub installs
Marketplace	~190 built-in skills, agents, compactors, and plugins plus an external marketplace (Open VSX) that only offers what Axion can run
Developer Tools	76 toolchains detected and installable, 46 debug adapters, and a PATH repair button
Language support	16 LSP capabilities — completion, go-to-definition, references, rename, code actions, signature help, formatting, outline, workspace symbols, folding, call hierarchy, inlay hints, semantic tokens, and expand-selection
Usage Analytics	Token spend, credits, and live provider balances
Report a Bug	A report dialog with the details filled in - and it opens itself when an error is thrown

The status bar at the bottom shows the live AI provider and model in use, with a green dot while the AI is working. It follows failover, so you can see which provider actually answered.

Three workspace modes

The flat button in the top bar cycles the workspace between:

1. ASSISTANT — chat-first. The AI Assistant tab is permanent.
2. DEVELOPER — assistant closed, editor front and center.
3. DESIGN — visual UI builder: drop widgets, edit properties, export to Avalonia XAML, HTML, or React (see Design Mode).

The selected mode is saved per workspace and restored when you reopen it.
