## Kaopu API

Kaopu API positions itself as "AI application infrastructure foundation" — a single gateway that sits between your application and the many large language models you want to use. Instead of wiring up a separate integration and billing account for every provider, you connect your API keys as channels, and Kaopu API exposes them through one standard, OpenAI-compatible protocol. The marketing highlights high-concurrency handling with automatic load balancing, so traffic can be spread across channels to keep services responsive.

Beyond routing, the platform doubles as an administration dashboard. You can configure channels, set access permissions, and run multi-user management with flexible roles from one central panel — useful when several developers or teams share the same infrastructure and need their usage and access kept separate. Billing is pay-as-you-go, with real-time usage monitoring and transparent cost tracking so you can see exactly where tokens and budget are being consumed.

Kaopu API is built on the open-source New API project, which means the gateway is self-hostable and extensible. Setup follows three straightforward steps: configure your keys and channels, connect through the compatible OpenAI, Claude, or Gemini routes, then monitor usage, costs, and performance with real-time analytics. Because it is a gateway rather than a model provider, its practical value comes from the upstream services you choose to connect.

**Pricing & Plans:** Pay-as-you-go model with real-time usage monitoring and transparent token-based billing inside the dashboard; since it is self-hostable, total cost also depends on the upstream providers you connect. Public per-token rates are not published on the site.

- **Single unified API endpoint:** Route requests to many upstream AI models through one standard, OpenAI-compatible API protocol, so your code stays the same as providers change.
- **Automatic load balancing:** High-concurrency handling with automatic load balancing spreads traffic across your configured channels to keep responses reliable.
- **Transparent token billing:** Pay-as-you-go accounting with real-time usage monitoring and clear per-key, per-model spending so you always know where budget goes.
- **Multi-user admin dashboard:** Add API keys, set up channels, and assign access permissions for multiple users from one central admin panel.
- **Open-source and extensible:** One-click configuration that adapts to the New API multi-protocol setup, plus a community-driven, self-hosted, extensible codebase.

**Strengths:** One OpenAI-compatible endpoint for many models reduces integration work; Automatic load balancing helps keep high-concurrency workloads responsive; Transparent pay-as-you-go billing with real-time usage and cost tracking; Multi-user management with flexible permissions suits teams sharing infrastructure

**Limitations:** Requires technical setup and self-hosting knowledge to deploy your own gateway; Pricing details are not published openly on the public site, so you must sign up or contact the team for costs; Its value depends on the upstream providers you connect; it does not supply models itself; Advanced multi-user and permission configuration may feel complex for solo developers

## LiteLLM

LiteLLM is an open-source AI gateway and Python SDK designed to remove vendor lock-in from LLM applications. The SDK lets you call models from OpenAI, Anthropic, Google Vertex AI, Bedrock, Mistral, Azure and dozens of other providers using the same OpenAI-style request format, so switching models is a configuration change rather than a code rewrite. The same project ships an AI Gateway (often called the proxy) that turns that abstraction into a shared service for an entire organization.

That gateway is where most platform teams find the value. It issues virtual keys scoped by team, project or application, tracks spend per key against budgets, applies rate limits (TPM and RPM), and exposes dashboards for request volume, token usage and cost per model. Routing features include load balancing across deployments, automatic fallbacks when a provider fails, retries and budget-based rerouting, plus guardrails for PII masking, prompt-injection detection and secret detection.

The project is genuinely open source with the code on GitHub (BerriAI/litellm) and a very active community. Enterprise features add SSO, audit logs, and support for agents and MCP servers through the same gateway. Notably, LiteLLM supports day-zero access to new models so teams can adopt them as soon as they ship, and it can also serve self-hosted, fine-tuned and internal models behind the same key. Companies cited on the site include NVIDIA, Netflix, Okta, Lemonade and AT&T.

**Pricing & Plans:** Freemium and open source. The self-hosted LiteLLM gateway and SDK are free under an open-source licence, and a free tier lets you get started immediately. Enterprise plans with SSO, audit logs, SLAs and advanced support are quoted on request via the sales team.

- **OpenAI-compatible API for 100+ LLMs:** Call 100+ providers and 1,800+ models using one request format, so you can swap models without changing application code.
- **Virtual keys, teams and budgets:** Issue scoped keys per team, project or app, set monthly spend caps and see exactly who is driving usage and cost.
- **Routing, load balancing and fallbacks:** Distribute traffic across deployments, retry on failure and automatically fall back to another model or provider when one goes down.
- **Observability and spend tracking:** Dashboards for request volume, tokens and cost per model, with support for logging and analytics integrations.
- **Guardrails and policy controls:** Plug in PII masking, prompt-injection detection and secret-detection guardrails, and manage policies centrally instead of in every app.

**Strengths:** Truly open source with a large GitHub community and self-hosting option; Very broad provider coverage with an OpenAI-compatible interface; Enterprise-grade controls: virtual keys, budgets, rate limits and audit logs; Day-zero support for new models and easy fallback when providers fail

**Limitations:** Self-hosting means you own deployment, upgrades and uptime; Feature depth varies between the free open-source version and enterprise plan; The breadth of configuration options can be overwhelming for small projects
