Foundry Local vs TextGen

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.

TextGen

AGPL-3.0 with no telemetry, and a local API on 127.0.0.1:5000 that checks the Host header, limits CORS to localhost and separates an admin key from the caller's key. No release since v4.9 on 20 May 2026, no code commits since 31 May, no test suite, and ten security advisories in the year, all fixed.

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

TextGen

1. Ask the owner to launch with --api. Nothing listens on port 5000 without it, and a model must be loaded first
2. Call http://127.0.0.1:5000/v1. Any Host header other than localhost or 127.0.0.1 gets 400 Invalid host header unless --listen is set
3. Send the key as Authorization: Bearer on OpenAI routes and as x-api-key on /v1/messages. Model loading needs the admin key
4. Read http://127.0.0.1:5000/docs or modules/api/typing.py for parameters. max_tokens defaults to 512 on chat completions
5. Run tool calls yourself. The API returns finish_reason: "tool_calls" and executes nothing on the server
6. Use the repository name oobabooga/textgen. The old text-generation-webui URL redirects
