Signal handles retries, streaming, rate limits, and model fallback so your team ships the feature, not the plumbing around it.
The parts every team rebuilds from scratch — solved once, so you don't have to.
If a model is down or rate-limited, requests reroute to a backup provider with no code changes.
Token-level streaming with backpressure handling, so your UI never gets ahead of the model.
Per-request cost, latency, and token breakdowns, filterable by user, feature, or model.
Exponential backoff tuned per provider, with idempotency so retries never duplicate side effects.
Every prompt change is tracked and diffable, so you can roll back a regression in one click.
Share rate limits across your team's keys instead of hitting separate provider ceilings.
This is a real sequence — each step depends on the one before it.
Point your existing SDK at api.signal.dev instead of the provider directly. No new SDK to learn.
Choose which models to try, and in what order, when the primary one fails or rate-limits you.
Every request, cost, and failure shows up live — filterable by feature, user, or model.
No seat fees. You pay for requests, not headcount.
For side projects and early prototypes.
For products live in production.
For high-volume, multi-team orgs.
