Conversation
Add OrcaRouter (https://www.orcarouter.ai) as a named alternative LLM gateway alongside OpenRouter. All model calls (schema inference, populate and refresh agents, model listing, key verification) resolve the active gateway from a small provider registry: an OrcaRouter key, or LLM_PROVIDER=orcarouter, switches the base URL to https://api.orcarouter.ai/v1 without changing the OpenAI-compatible request path. - backend: llm-provider.ts registry, gateway-aware credential resolution (getLlmBaseUrl/requireLlmApiKey), /local-setup/orcarouter-key and /local-setup/llm-provider routes, provider-aware key verification - frontend: OrcaRouter card in setup and settings credential panels, saveOrcaRouterApiKey/saveLlmProviderApiKey helpers, orcarouter service status - env: ORCAROUTER_API_KEY and LLM_PROVIDER wired through .env and docker-compose.dev.yml; README/CLAUDE.md updated Co-Authored-By: Claude <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe change adds OrcaRouter as an alternative LLM gateway. It adds provider selection, endpoint resolution, API-key verification, keychain storage, setup-status reporting, and local setup endpoints. Model discovery, agents, workflows, and schema inference use the active provider. Docker configuration passes the new environment variables. The setup page and credentials panel provide OrcaRouter key entry and status display. Documentation describes OrcaRouter configuration. Sequence Diagram(s)sequenceDiagram

Suggested reviewers: Merge Risk: 🟡 Moderate · up to The PR adds OrcaRouter selection across setup, credentials, and model usage, but switching gateways can currently expose stale OpenRouter model listings instead of the active provider’s models, leading to incorrect model choices. This bounded correctness issue should be addressed or explicitly accepted before merge; the remaining documentation updates are minor follow-up work. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Key the model cache by the active gateway.
api.openRouterModels.list returns all globally cached rows, and getCachedModels() returns them before calling fetchModelsFromOpenRouter(). Because the rows have no provider identity, switching from OpenRouter to OrcaRouter can return stale OpenRouter models without querying OrcaRouter. Store the provider ID with each row or invalidate the cache when the active provider changes.

Update the setup steps for OrcaRouter.
This paragraph says that OrcaRouter can replace OpenRouter, but the numbered steps still require an OpenRouter key and tell users to paste both TinyFish and OpenRouter credentials (Lines [229-231]). Change the heading and steps to require TinyFish plus one LLM gateway, and add the OrcaRouter key instructions.

What
BigSet already routes all of its AI model calls — schema inference, the populate/refresh agents, model listing, and setup key verification — through a single OpenAI-compatible gateway, OpenRouter. This PR adds OrcaRouter as a first-class alternative gateway, mirroring the existing OpenRouter wiring instead of treating OrcaRouter as an anonymous custom base URL.
OrcaRouter is an OpenAI-compatible AI gateway built for both models and agents. Like OpenRouter, it exposes a provider/model namespace across many models — but it also combines adaptive routing, automatic failover, zero-markup inference, observability, guardrails, and agent-tool governance behind the same endpoint. Adding it as a named provider means BigSet users can use that stack directly. It also runs gateway-level, zero-trust security for AI agents on the same endpoint — screening every prompt/response and governing every tool call on a default-deny basis, with no application code changes.
How it works
backend/src/config/llm-provider.tsregistry names the two gateways (openrouter/orcarouter), each with its own base URL and key-verification endpoint.getLlmBaseUrl()/requireLlmApiKey()pick the active provider from anORCAROUTER_API_KEYcredential orLLM_PROVIDER=orcarouterin.env, falling back to OpenRouter.https://api.orcarouter.ai/v1/models), alongside the existing OpenRouter card.anthropic/claude-sonnet-4.6resolve through whichever gateway is active.Verification
