## 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

## GuRouter

GuRouter positions itself as a next-generation AI gateway for teams that juggle multiple model vendors. Instead of maintaining separate accounts, keys and billing relationships across OpenAI, Anthropic, Google, DeepSeek and others, developers point their code at a single OpenAI-compatible base URL and let the router dispatch each request to the model that best fits the task. The platform advertises more than 40 supported models, including recent DeepSeek and OpenAI releases, alongside Claude and Gemini families.

The commercial pitch is transparency: GuRouter states it applies zero markup to underlying model token costs and instead charges through micro-cent level accounting, so a high-volume workload billed in fractions of a cent per call stays predictable. It also functions as a model discovery surface, letting builders compare live pricing across providers before committing an application to a specific model, and offers a catalog that includes free or low-cost models for experimentation.

Beyond raw chat completions, GuRouter targets the coding-agent ecosystem, listing compatibility with tools such as OpenCode, Claude Code, Cursor and Cline. That makes it attractive to solo developers and small teams who want one credential and one invoice to power CLI agents, IDE assistants and production services alike, while keeping the option to swap models without rewriting integration code.

**Pricing & Plans:** Freemium. The gateway advertises zero markup over underlying model token costs with micro-cent, pay-per-request billing; some models are available at no charge. A free tier is offered for exploration, and exact rate cards should be checked on the provider's live model pricing page.

- **Unified OpenAI-compatible API:** Swap in a single base URL and API key to reach dozens of chat and reasoning models without rewriting SDK integration code.
- **Zero-markup routing:** GuRouter states that requests are passed through at underlying model token prices, with micro-cent billing granularity rather than bundled credit packages.
- **Broad model catalog:** Access to 40+ models spanning OpenAI, Anthropic, Google, DeepSeek and Qwen families, including frontier and economical options.
- **Coding-agent ready:** Documented compatibility with agent tooling such as OpenCode, Claude Code, Cursor and Cline for CLI and IDE workflows.
- **Live price comparison:** Compare per-token costs across providers directly in the gateway to decide which model an application should default to.

**Strengths:** Single OpenAI-compatible endpoint removes multi-vendor integration overhead; Stated zero markup and micro-cent billing keep cost accounting granular and transparent; Broad catalog spanning frontier, economical and free models; Native fit for coding agents and IDE assistants

**Limitations:** Adds a routing dependency in front of your model traffic; Costs ultimately track underlying provider pricing, which changes frequently; Gateway-specific quotas, availability and free-tier limits should be verified on the live site
