Which one, for what

Foundry Local C

Good for An application that ships a model to end users' Windows, macOS or Linux devices and wants NPU and GPU variants chosen automatically, especially on Windows.

Ahead on

  • Maintenance & community, 88 against 80
  • Transparency & trust, 72 against 47

Also in its favour

  • No key needed to call it
  • No incidents deducted, where LocalAI loses 3 points for them

Watch for

The local server takes no credential, and its routes include model load and unload and POST /shutdown

LocalAI B

Good for An owner who wants one local server for chat, embeddings, reranking, speech, images and video behind APIs their existing OpenAI, Anthropic or Ollama clients already speak, on almost any accelerator.

Ahead on

  • Reliability, 84 against 68
  • Schema & documentation, 81 against 53
  • Agent ergonomics, 71 against 61
  • Security & auth, 62 against 39

Also in its favour

  • Runs on your own machine

Watch for

No authentication by default. Loopback, LAN and VPN binds answer every caller, and keys set by environment variable grant full admin

Verdicts

Foundry Local

The SDK and its native runtime are MIT, at 2.1.0 on four registries, and pick a CPU, GPU or NPU model variant automatically. The optional local server has no credential, its current routes aren't in the published REST reference, and telemetry is on by default with an opt-out.

LocalAI

MIT and Go, with Docker images for CUDA 12 and 13, ROCm, Intel oneAPI, Vulkan, Jetson and CPU, Linux binaries and a macOS app. No authentication by default. Loopback, LAN and VPN binds answer every caller, and keys set by environment variable grant full admin.

Before you call either

Foundry Local

  1. Read the server URL from manager.urls[0] or foundry server status. The port is dynamic unless the owner sets web.urls or foundry server start --port
  2. Send the model ID that GET /v1/models returns, not the alias. The alias resolves to a hardware-specific variant
  3. Check supportsToolCalling before sending tools. Support differs by variant, and issue #1183 reports Qwen tool calling failing on QNN
  4. Set your own request timeout. Inference has no built-in one, and cancellation takes effect only after the current generation step
  5. Ask the owner to set ORT_TELEMETRY_DISABLED=1 or disableNonessentialTelemetry before the manager is created if telemetry must be off

LocalAI

  1. Send Authorization: Bearer <key> when the operator has set keys. A 401 means the instance has auth on
  2. Read /.well-known/localai.json and /api/instructions first. Both answer without a key and list what this instance can do
  3. Back off on 429 and 503 for the Retry-After seconds. A 503 can mean the model is still loading
  4. Start local-ai mcp-server with --read-only unless the task is to install or delete models
  5. Take model names from /v1/models. Each instance names its own

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
