KeepRouter

KeepRouter is a cloud API gateway for developers who want one account and integration across models from multiple providers. It is strongest for usage-based projects that value published model rates and broad output modalities; teams wanting recurring subscriptions or prompt-content logs should consider alternatives.

Overview

KeepRouter's production catalog contains 101 models from multiple makers, with customer prices and supported endpoints shown for each. That breadth lets developers compare text, image, video and speech options behind one service, while modality-specific billing reflects how each type of output is charged. Consumer and latency analytics are included, but business activity metrics are not, so it is better suited to technical usage oversight than company-wide activity reporting.

The gateway runs on Cloudflare's global edge network. KeepRouter says customer data is not used to train models, and business customers can contact support about a DPA. Paddle acts as Merchant of Record for top-ups, invoices and tax, which centralizes payment administration for international buyers.

Key features

OpenAI and Anthropic compatibility

Supported chat models accept OpenAI Chat Completions requests at /v1/chat/completions. They can also accept Anthropic Messages requests at /v1/messages, including use with Claude Code and the Anthropic SDK. Existing applications using either interface can therefore change the base gateway without adopting a wholly new request style, although endpoint support is model-specific and should be checked before rollout.

Multimodal catalog

Text, image, video and speech-output models appear in one catalog. Pricing units differ by modality: text is charged per token, while image models may be priced per image or token and video and speech by duration. This suits teams with mixed workloads, but forecasting spend requires understanding each model's unit rather than applying one universal rate.

Free model and integrations

The model named free charges $0.0000 per 1M input tokens and $0.0000 per 1M output tokens. It supports chat completions, streaming where supported and tool calling where supported, making it useful for evaluation and prototypes without token charges. Configuration guidance is provided for OpenCode and Continue through KeepRouter's OpenAI-compatible base URL.

Billing, keys and observability

Paid usage comes from prepaid USD credit with no recurring subscription. API keys can be restricted to model allowlists, a practical safeguard for separating workloads. The raw sk-kr- key appears only once at creation, so operators must store it securely at issuance. Request logs record timestamp, model, route, HTTP status, token counts, cost, cache state and latency without retaining prompt or completion bodies. That gives useful operational and cost visibility while limiting content exposure.

Keys are stored only as SHA-256 hashes and requests authenticate over HTTPS with TLS. Response caching is off by default; when enabled, identical non-streaming requests may be cached transiently in Cloudflare KV. Enable it only where repeated responses and transient edge storage fit the application's requirements.

Pricing

The free plan removes token charges but is explicitly best-effort, so it should not be treated as a reliability commitment. Paid use requires topping up credit before requests consume it; buyers who prefer automatic monthly renewal or a fixed allowance will find the model less convenient. Paid pricing starts from $0.02, while the final amount depends on the selected model and modality.

Platforms

KeepRouter is delivered as a cloud service through web and API access. Its OpenAI-compatible base URL supports documented OpenCode and Continue configurations, while Anthropic-compatible requests support Claude Code and the Anthropic SDK.

Who it's for

Choose KeepRouter when you need one gateway for many providers, want to compare 101 publicly priced models, or run workloads spanning text, images, video and speech. It also fits teams that need latency and cost records without storing prompt bodies, and businesses that may require a DPA discussion.

Look elsewhere if your operation depends on business activity metrics, guaranteed service levels for free usage, recurring-plan billing, or retained prompt and completion content for deeper analysis.

Pros and cons

• Pro: One account and compatible OpenAI and Anthropic routes reduce integration changes across providers.
• Pro: A 101-model, multimodal catalog with public rates supports direct cost and capability comparison.
• Pro: Prepaid, non-recurring billing avoids subscription commitments.
• Pro: Allowlisted keys, one-time raw-key display, hashed storage and body-free request logs strengthen operational control.
• Con: Free usage is best-effort, so it is unsuitable as a dependable production tier.
• Con: Prepaid credit and modality-specific units make budgeting less predictable than a fixed subscription.
• Con: No business activity metrics and no prompt/completion bodies limit business reporting and content-level investigation.

Alternatives

For a broader directory of monitoring tools, see API Analytics Software. Choose AI Nazar instead if self-hosting and MIT-licensed open-source SDK and dashboard matter. API Analytics fits users wanting a free, self-hosted option with up to 1 million stored requests per user.

Apirelio is preferable when you need project, event-retention and member limits in paid Growth or Scale plans. BetterMeter offers API and web access with a free plan and 30-day event retention. Pick Clavio for browser-based analysis of sample datasets and uploads with limited saved analyses on its free tier.

Helicone suits teams wanting an open-source API observability service with a free request allowance. Langfuse is the alternative when self-hosting, 50k included monthly units and multi-user data access are priorities. Moesif is another API analytics option with a free plan after its trial.

Verdict

KeepRouter is a strong choice for developers consolidating multi-provider model access behind compatible APIs, especially when multimodal selection and prepaid, non-recurring billing matter. Look elsewhere if you need business-level activity reporting, dependable free-tier service or logs that retain request content for analysis.
