Plano
Envoy-based data plane for AI agents that handles routing, guardrails, and observability outside your app code.
In short
Plano acts as a framework-agnostic infrastructure layer between agents and LLMs, handling routing, policy enforcement, and observability. It is best for engineering teams needing production-grade traffic management and centralized guardrails without embedding logic in app code.
Pick Plano if you're running agents in production and want routing, guardrails, and observability as a dedicated data plane instead of per-framework SDKs.
Skip it if you just want a hosted agent builder or a coding assistant; this is plumbing for engineering teams, not a turnkey product.
Plano is an AI-native delivery infrastructure for agentic applications, originally built by Katanemo Labs and now acquired by DigitalOcean. It sits between your agents and the LLM/tool layer as a framework-agnostic, protocol-native fabric, handling smart model routing, multi-agent orchestration, context engineering filters, jailbreak detection, and centralized policy enforcement from a single configuration file.
What differentiates Plano is that it is built on Envoy, the same battle-tested data plane proxy used by service meshes like Istio. That gives it production-grade traffic handling out of the box and lets teams move agent infrastructure concerns (routing, guardrails, traces) out of the application code and into a dedicated control plane. It's aimed at engineering teams running agents in production who want observability and policy as cross-cutting infrastructure rather than per-framework SDK glue. Pricing is not published; the project has an open-source repo and on-prem deployment is supported, with commercial offerings presumably arriving via DigitalOcean.
It is framework-friendly (works alongside whatever agent framework you're using) and language-flexible, and emits production signals usable for reinforcement learning loops. Caveat: this is infrastructure for builders, not a turnkey agent product, so expect to invest in configuration and deployment.
Plano's Envoy lineage is the tell: this is serious infra for teams treating agents like real distributed systems, not a demo. The DigitalOcean acquisition signals it's likely to keep shipping, but you'll want to weigh the operational overhead against rolling your own gateway.

- ✅ Built-in guardrails, jailbreak detection, and centralized policies
- ✅ Open source with on-prem deployment supported
- ✅ Backed by DigitalOcean after acquisition
Cons
- ⚠️ Infrastructure layer, not a finished agent product
- ⚠️ Pricing for managed/commercial tier not disclosed
- ⚠️ Requires ops maturity to deploy and operate Envoy-based fabric
Use cases
Frequently asked
- What is the core technology behind Plano?
- Plano is built on Envoy, the same data plane proxy used by service meshes like Istio. This provides production-grade traffic handling and allows infrastructure concerns to be managed outside application code.
- Is Plano compatible with specific agent frameworks?
- Yes, Plano is framework-agnostic and language-flexible. It sits alongside whatever agent framework you are using, acting as a protocol-native fabric rather than requiring specific SDK integration.
- What security features does Plano offer?
- The platform includes built-in guardrails, jailbreak detection, and centralized policy enforcement. These features are managed from a single configuration file to ensure consistent security across agents.
- Is Plano available for free?
- Plano is open source and supports on-prem deployment. While commercial pricing is not disclosed, the project is backed by DigitalOcean following its acquisition.
- Who is Plano designed for?
- It is aimed at engineering teams running agents in production who want observability and policy as cross-cutting infrastructure. It is not a turnkey agent product or hosted builder.
