## AIProxy

AIProxy solves a problem that shows up in almost every mobile app that uses AI: an API key embedded in a shipped app is effectively public. Instead of building and maintaining your own backend, you register with AIProxy, receive a partial key plus a service URL, and call the provider through the proxy. Real keys stay encrypted server-side, and abuse protection is handled for you.

The platform bundles security with day-to-day operational tools. Requests are checked against rate limits you configure, usage shows up in a realtime dashboard with notifications for suspicious activity, and a live console lets you replay and inspect calls. Model overrides let you swap the underlying model, or route users to their own keys, without shipping an app update.

AIProxy supports 15+ providers including OpenAI, Anthropic, Gemini, Replicate, ElevenLabs and Mistral, and ships an open-source Swift client library (AIProxySwift) so an integration typically takes under ten minutes. It runs on AWS and scales horizontally, with a free starter plan and paid tiers for production traffic.

**Pricing & Plans:** Free plan available with no credit card required, plus paid tiers for higher traffic and advanced features. Exact tier pricing is listed on the AIProxy pricing page.

- **Key and endpoint protection:** Split key encryption, DeviceCheck and certificate pinning work together so your API key and service endpoint cannot be lifted from network traffic or the app bundle.
- **Rate limiting builder:** Set threshold limits per endpoint from the dashboard; requests that exceed your rules are refused before they spend your provider credits.
- **Realtime observability:** A usage dashboard plus notifications surface suspicious activity and help you understand how users interact with AI features in your app.
- **Live console and model overrides:** Test and replay API calls from the dashboard, and change the model your app uses without submitting a new build.
- **Swift client library:** AIProxySwift is an open-source package that wraps 15+ AI providers with a consistent async/await API for fast integration.

**Strengths:** Removes the need to build and operate your own proxy backend just to hide keys; Security features such as DeviceCheck and certificate pinning are configured, not custom-built; Open-source Swift library makes integration fast for Apple-platform developers; Dashboard tooling covers monitoring, alerts and model changes in one place

**Limitations:** Adds a third-party hop between your app and the AI provider, which some teams prefer to avoid; Client tooling is Swift-first, so other stacks need to call the HTTP proxy directly; Advanced security and observability sit behind paid plans

## Flatkey

Flatkey positions itself as a drop-in replacement for the base URL you already use. Because the endpoint is OpenAI-compatible, an existing SDK or code path usually keeps working after you swap the URL and paste a Flatkey key. Model selection happens per request through the model ID, which means switching between labs does not require a new account, new keys, or new integration code.

Beyond raw chat completions, Flatkey aggregates utility and creation tools behind the same auth layer. Governance features are aimed at teams running agents in production: hierarchical sub-keys carry their own budgets, model allowlists, and tool permissions, and a ledger API records usage per request so spend can be attributed to a specific agent or project. A published service level agreement, channel-class failover, and the promise that Flatkey-side errors are not billed are the commercial core of the pitch.

The site advertises discounts on featured models against official list pricing, hourly verification that requests reach genuine lab endpoints, GDPR-related commitments, and zero retention of request payloads. Pricing is not published as fixed tiers, so prospective customers are expected to sign up free or contact sales for volume terms.

**Pricing & Plans:** Paid gateway with prepaid balance billing; the site pushes a free trial and directs larger buyers to sales. No fixed public plan tiers are shown on the homepage, and model prices are listed per million tokens against official list rates.

- **One OpenAI-compatible endpoint:** Point your existing SDK at Flatkey's router URL and select models by ID instead of managing a credential per provider.
- **Unified model and tool routing:** Frontier chat models and 1,000+ pay-per-call tools share one auth layer, one balance, and one invoice.
- **Sub-keys with budgets and allowlists:** Issue scoped keys per agent or environment, capped by spend and restricted to approved models and tools.
- **Automatic failover and a published SLA:** Requests route across five channel classes; when one degrades the router reroutes, backed by a 99.5% SLA document.
- **Per-request ledger and zero-charge failures:** Every call gets a request ID and usage record, and errors caused on Flatkey's side are billed at $0.

**Strengths:** OpenAI-compatible interface means minimal migration effort; Single balance and invoice across models and utility tools; Budgeted sub-keys and allowlists suit multi-agent production setups; Failed calls on the provider side are not charged, per the stated SLA

**Limitations:** No fixed public pricing tiers, so budgeting requires a sales conversation; Routing layer adds a dependency between your app and the model labs; Value depends on the discount and reliability claims holding up in practice
