A declarative fallback chain across every provider you trust, with sub-second cut-over and a live event stream of every retry. Chain three providers and a single outage never reaches your users.
Provider outages, regional rate limits, model deprecations, content-filter false positives — all of them surface as 5xx in your app. Most teams handle this by stitching together a try/catch ladder per provider, then hoping the on-call engineer remembers it exists.
Routero AI replaces that with a declarative fallback chain, sub-second failover, and a live view of which provider actually served each request.
Every provider+model is probed every 10s — latency, error rate, content-filter trip rate. A degraded provider is marked unhealthy before your users notice.
5xx, rate limit, content filter, context window, auth — each triggers a different retry strategy. A 429 retries on the same provider; a content-filter trip jumps to the fallback.
If a streaming request fails before output starts, it is immediately retried on the next candidate. Your client sees one complete, continuous SSE stream.
Fallback chains respect spend policies. A "cost-optimized" route won't fall back to GPT-4 unless you opt-in. A "quality-first" route will.
EU-region gateways only peer with EU providers; US-region data stays US-only. Self-hosted models are only called from inside your VPC — even during a global outage.
Every response carries headers showing the chosen provider, retry count, and decision reason. Reproducible incidents, no log spelunking.
A typical production route. Anthropic primary, OpenAI mid, an in-region open-source model as last-resort. Routero AI walks the chain on any unrecoverable error.
A live event stream of every routing decision, with filterable views for SRE on-calls. Click any failover event to see the provider's health snapshot at that moment — no after-the-fact reconstruction.
Recent failovers are highlighted. Anthropic returned overloaded_error twice in this minute; OpenAI handled both retries cleanly.
