OnAPI vs keel

OnAPI is a unified API gateway that lets developers call GPT, Claude, Gemini, Sora, Veo, and Google's Nano Banana image model through a single key. Swap your SDK base URL to OnAPI's endpoint, plug in an OnAPI key, and keep the rest of your integration unchanged.

The gateway speaks OpenAI-compatible and Anthropic-compatible protocols, so chat completions, Anthropic messages, streaming, function calling, and long-context requests work without a rewrite. OnAPI says new upstream models typically appear within 24 hours of release.

Two routing channels share the same account. The economy channel bills at a 1:1 rate multiplier for everyday volume. The official channel routes through paid keys tied directly to provider accounts at a 1:7.5 multiplier when you need a straighter path to upstream APIs.

OnAPI is aimed at builders shipping AI products, especially where direct provider billing is inconvenient. Top-ups run through Alipay, WeChat, USDT, and USDC. Account balance does not expire, and the site states there is no minimum spend.

The service runs on the open-source New API project (based on One API), which handles model aggregation and cross-format conversion between provider APIs.

Keel is an operations platform that lets teams build custom software to run inventory, orders, warehouse workflows, and production planning without defaulting to a traditional ERP. Operators define their own data models, launch tailored systems in weeks, and connect the tools they already use.

The platform is code-first at its core. Teams describe data, APIs, permissions, and jobs in a Keel schema, then get managed serverless Postgres, auto-generated GraphQL and JSON APIs, TypeScript extensions, and internal admin tools from the same source of truth. Keel is open source and built for version control, multiple environments, and local development with its CLI and VS Code extension.

Keel was founded in 2021 by former Echo executives who scaled pharmacy operations through custom internal tooling when off-the-shelf software fell short. The company raised $6 million in 2024 to bring the platform to more operations teams who have outgrown spreadsheets and no-code stacks but want to avoid lengthy ERP implementations.

It suits logistics companies, e-commerce operators, manufacturers, and other teams that need owned, adaptable ops software their own staff can iterate on without waiting months for engineering priority.
