Squiid vs Inworld Realtime Router
Inworld Realtime Router decides which model answers a request: routing rules, A/B tests, failover, 0% on routed third-party models. Squiid covers the rest of the app.
Short answer. If model selection is the hard part of your project, the Realtime Router is the better and cheaper tool: 0% published markup on routed third-party models, CEL routing rules, sticky A/B tests, failover and text to speech behind one endpoint. Squiid does none of that. It provisions the database, host, email sender, phone number, storage and auth the same app needs.
The one-line difference. The Realtime Router decides which brain answers. Squiid answers what the app needs to exist around it. One replaces your model provider list, the other replaces your signup list.
Side by side
| Inworld Realtime Router | Squiid | |
|---|---|---|
| What it covers | Models. One endpoint over 220+ models with rule-based routing, A/B tests, failover and text to speech, plus Inworld first-party inference and voice. | The whole catalogue: databases, hosting, email, SMS, storage, auth and payments, models included. Model calls go to a named provider, not a router. |
| Non-AI services | No. Outside its scope by design. | Yes. Postgres, object storage, email, phone numbers, error tracking. |
| Provisioning of accounts | No accounts to create for routed models: the endpoint is the account. Nothing outside models is provisioned. | Yes. Squiid opens the account and holds the credential. |
| Key custody and rotation | One Inworld key for model traffic. Every other credential stays where it was. | Squiid holds and rotates the provider keys. Your project carries one gateway key, worthless outside it. |
| Billing model | Routed third-party models pass through with 0% markup. Inworld monetises its own inference and voice instead. | Prepaid credits at par: $1 of credit is $1 at the provider. Subscriptions pass through at list price. |
| Fee | 0% on routed third-party models, as published on their router page. | Free $0/mo + 15% at top-up. Solo $19.97/mo from 8%, falling to 3.5% with spend. Team from $29.97/seat, one point lower. Custom 3% or less. |
| One invoice PDF | One bill for model and voice traffic. Every other vendor invoices separately. | Yes. One monthly PDF: credits, plan, subscriptions. |
| Spend caps and pause-on-zero | Traffic rules, failover and A/B assignment per request. Spend limits apply to model usage only. | Yes. Alerts at 75, 90 and 100%, capped auto top-up, pause at zero. |
| Works with coding agents | Yes. One-variable setups published for Cursor, Claude Code, Codex and Windsurf. | Yes. One variable and one base URL convention for every service. |
| Self-host option | Hosted. No self-hosted edition on their router page. | No. Hosted only. Leaving is a transfer where the provider supports one, a documented export otherwise. See handover. |
| Best for | Per-user model routing, sticky experiments and voice behind one endpoint. | Projects where the model bill is one line next to the database. |
When to pick Inworld Realtime Router instead
Pick it when the interesting decisions in your product are model decisions. CEL routing rules branch on user traits, so free users land on a cheap model and paying users on a frontier one without a deploy.
Pick it to run experiments properly. A/B tests with sticky assignment keep the same person on the same variant, and cross-provider failover mid-request is the same kind of value.
Pick it on price if models are all you buy, and for voice. 0% on routed third-party models is hard to beat, and text to speech behind the same endpoint removes a second vendor for anything that talks.
When Squiid is the better fit
Squiid is the better fit when the model is the easy part. Most vibe-coded apps reach production with Postgres, a host, email, storage, error tracking and payments, then a model provider. The router covers the last item.
It is also the better fit for key custody. A router holds your model credential while the database URL, SMTP key and Stripe secret sit in a .env file an agent can read. Squiid holds all of them upstream.
And it is the better fit if what you want is one invoice: one monthly PDF instead of eleven receipts in eleven formats.
Use both
A good pair, because the overlap is small. Model traffic to the Realtime Router; everything else to Squiid, from the Postgres project to the auth tenant. Two environment variables instead of twelve. If you would rather have one invoice than the best routing, Squiid carries the major model providers directly.
Questions people ask
Is Inworld Realtime Router cheaper than Squiid for model calls?
For model calls alone, yes. They publish 0% markup on routed third-party models; Squiid is 15% on the free plan, or $19.97 a month plus 8% at top-up on Solo, falling to 3.5% as spend grows. If inference is all you buy, the router wins on price.
Does the Realtime Router give me a database or an email sender?
No, and it does not claim to. Databases, hosting, email, SMS, storage and auth are what the Squiid catalogue is for.
Can Claude Code use both at once?
Yes. Both are environment variable changes: model client at the router, everything else at https://api.squiid.io/v1/<service>/ with a bearer token.
Does Squiid do CEL routing rules or A/B tests on models?
No. Squiid calls a named provider through a named gateway path. For routing by user trait, sticky variants or mid-request failover, use a router that specialises in it.
What about voice, since Inworld bundles TTS?
Squiid carries ElevenLabs, Deepgram and AssemblyAI on the same prepaid balance. Inworld bundles its own voice with routed inference, which is tidier if you want one vendor for both.
