Cadenya vs oMLX: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Cadenya and oMLX — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Cadenya
Cadenya
A managed agent runtime that layers your tools, agents and objectives so teams can test agent behavior safely and iterate fast.
Key features
- Unified Tool Layer: Connect MCP servers, OpenAPI specs and existing endpoints once, and expose them to every agent through a single managed interface.
- Model-Agnostic Variations: Set a default model and run canary variations on other providers side by side to compare behaviors before promoting a change.
- Progressive Tool Discovery: Tool schemas stay out of the context window until an agent asks for them, with configurable max tools per search, search hints and a rerank threshold, so every request gets smaller.
- Live Token Metering: Track cost as it accrues across loops, active variations, memory entries and widgets, so usage is visible rather than discovered on the invoice.
- Webhooks and SSE Streaming: Push agent events — assistant messages, tool results, approval requests, sub-agent spawns, compaction, timeouts — into your own apps in real time.
- Memory Layers: Attach stored documents such as playbooks and policy sets to an agent so its guidance persists across objectives.
- Outcome Feedback Scoring: Collect scored comments on each objective, attributed to the variation and model that produced it, to see which behaviors actually work.
- Embeddable Widgets: Drop an agent experience into any frontend as a widget rather than building the conversational surface yourself.
Best for
- Operational Exception Handling: Run an agent that detects stalled shipments or orders and reroutes them through your dispatch API within policy.
- Safe Model Migration: Evaluate a new frontier model as a canary variation against live objectives before switching the default.
- Wrapping Existing APIs: Turn internal OpenAPI endpoints into agent-callable tools without rewriting the services behind them.
- Embedding Agent Chat in a Product: Ship a conversational agent surface into an existing frontend using widgets instead of building it in-house.
- Cost Control at Scale: Use progressive discovery and live metering to keep context size and per-loop cost down as agent traffic grows.
- Agent Quality Review: Compare scored feedback across variations to understand which prompt or model changes improved real outcomes.
oMLX
Jun Kim
An open-source native macOS LLM inference server built on MLX whose paged SSD KV cache drops coding-agent time-to-first-token from 30-90s to under 5s.
Key features
- Paged SSD KV Caching: Cache blocks persist to disk in safetensors format with hot blocks in RAM and cold blocks on SSD, so previously seen prefixes are restored in milliseconds and survive server restarts.
- Sub-5s Agent TTFT: Cuts time-to-first-token for coding agents from 30-90 seconds down to under 5 seconds from the second turn onward.
- Continuous Batching: Handles concurrent requests through mlx-lm's BatchGenerator, measured at up to 4.14x generation speedup at 8x concurrency.
- OpenAI and Anthropic Drop-In API: Serves both OpenAI-compatible endpoints and a native Anthropic /v1/messages endpoint so Claude Code, OpenClaw, and Cursor connect without adapters.
- Multi-Model Serving: Loads LLM, VLM, embedding, and reranker models at the same time with LRU eviction when memory is constrained.
- Native Menu Bar App: A signed and notarized macOS app with in-app auto-update to start, stop, and monitor the server, plus a web dashboard for model management and live metrics.
- Tool Calling and MCP: Supports JSON, Qwen, Gemma, GLM, and MiniMax tool-calling formats with MCP integration and configurable trimming of oversized tool results.
- Config Command Generation: The dashboard emits the exact configuration command for each supported client tool.
Best for
- Local Coding Agents: Run Claude Code or OpenClaw entirely against a local model without the 90-second waits that make local inference impractical for agents.
- Private Codebase Work: Keep proprietary source on-device by pointing an OpenAI-compatible IDE assistant at a local endpoint.
- Offline Development: Continue agent-assisted coding without network access or per-token API costs.
- Model Benchmarking: Compare Qwen3.5-122B, Qwen3-Coder-Next, MiniMax-M2.5, and GLM-5 throughput on the same Apple Silicon hardware.
- Multi-Client Serving: Serve several concurrent agent sessions from one Mac using continuous batching rather than queuing behind a single request.
- RAG on a Mac: Host an LLM alongside embedding and reranker models in a single process for local retrieval pipelines.
