Which workflow fits?
Both tools are open-source AI coding agents that integrate with the Language Server Protocol (LSP). OpenCode emphasizes agile daily coding with fast Plan/Build tab switching across dozens of hosted cloud APIs. AX Code emphasizes engineering rigor on complex codebases: it pairs live LSP compiler diagnostics with a persistent SQLite code graph, an incremental repository architecture wiki (ax-wiki), test-verified Arena candidates in isolated worktrees, and local hardware acceleration via AX Engine.
| Consideration | AX Code | OpenCode |
|---|---|---|
| Live LSP & compiler feedback | Dual-layer intelligence: live LSP servers feed compiler diagnostics (diagnosticsAggregated) and symbol hierarchies directly into the model loop for instant self-correction, complemented by a persistent SQLite code graph for blast radius analysis. | Deep Language Server Protocol integration providing live compiler diagnostics and syntax errors back to the model for rapid edit-and-fix loops. |
| Repository architecture & knowledge | Native compiler (@automatosx/ax-wiki) builds an incremental Markdown wiki (ax-wiki/) from source diffs, with protected human maintainer blocks and agent wiki cards (AGENTS.md) for architectural grounding. | Relies on standard markdown instructions (e.g. AGENTS.md / rules) and manual repository file exploration without an automated incremental architecture wiki. |
| Verification & candidate ranking | Arena implement mode runs candidate solutions in isolated Git worktrees and checks them against repository test suites, ranking verified patches first before any merge. | Interactive Plan/Build mode switching with command execution and manual or automated test runs in the main workspace. |
| Recovery & auditability | Git-object snapshot rollback (ax-code rollback --step N) and structured execution graphs (ax-code graph), OTLP telemetry and audit logging. | Standard undo/redo commands (/undo and /redo) relying on git working tree state. |
| Model deployment & privacy | Local inference with AX Engine (optimized for Apple Silicon / MLX, achieving 76.9+ tokens/s on M5 Max), plus supported cloud providers and CLI adapters (Claude Code, Codex, Grok, Kimi). | Native presets for 75+ cloud providers (Claude, GPT, Gemini, DeepSeek, etc.) and local models via Ollama or custom endpoints. |
What to evaluate with AX Code
AX Code Standard is open source under Apache-2.0. Its terminal workflow supports connected local or cloud models, recorded execution, file-change review and session comparison. Local model performance depends on your hardware and selected model. External services may charge for usage.
AX Code Business is planned. The website’s illustrative speed display is not a benchmark against OpenCode.
Inspect AX Code’s source and documented capabilities ↗Does AX Code support live LSP compiler diagnostics like OpenCode?
Yes. AX Code includes full Language Server Protocol (LSP) integration alongside its persistent code graph. When an agent edits code, diagnosticsAggregated delivers live compiler warnings and type errors directly into the execution loop, enabling immediate self-correction before completing turns. It also provides go-to-definition, reference finding, hover documentation, and call hierarchies across TypeScript, Rust, Go, Python, and other major languages.
Try a representative task
Give both tools a refactoring task that triggers compiler type mismatches across multiple files. Observe how each agent receives compiler diagnostic feedback, whether it understands the transitive blast radius, and how it handles architectural conventions and verification.
