Portkey

Portkey

Portkey is an open source production stack for generative AI, and its community has made it one of the most adopted tools among teams shipping AI to production. With thousands of GitHub stars and more than 3,000 GenAI teams already relying on it to process trillions of tokens daily, Portkey has the kind of real-world validation that closed-source alternatives struggle to match. For engineers who value transparency, the open source nature of the platform is both a trust signal and a practical advantage.

Because the code is open, teams can inspect exactly how the AI Gateway routes calls, how observability captures data, and how guardrails enforce policy — there is no black box between a team and the infrastructure running its AI. The gateway provides unified access to over 1,600 LLMs through a single API, observability surfaces real-time dashboards for monitoring LLM behavior, prompt management removes hard-coded prompts, and governance adds the controls enterprises expect. Each module benefits from community feedback and contributions, which keeps the platform aligned with how teams actually build.

Portkey also meets teams where they already work. It integrates with Microsoft Azure, MongoDB, GitHub, Docker, and Auth0, so it slots into existing developer workflows instead of demanding a new stack, and its recent acquisition by Palo Alto Networks points toward continued investment in enterprise-grade security and governance. For the open source community of Gen AI builders, that combination — transparent code, a large active user base, and first-class integrations — makes Portkey a natural default. It is a no-brainer for teams that want production AI tooling they can trust, inspect, and extend on their own terms.
