Sovereign AI code execution, secure by default.

KEVLAR runs untrusted AI-generated code and agentic workloads inside hardened, isolated sandboxes — with zero data retention and full European data sovereignty. Ship autonomous agents without shipping your data offshore.

Launch console Compare tiers

No credit card. Anonymous developer tier available in-console.

Zero retention

EU data sovereignty

gVisor isolation

70–90% gross margin

A runtime built for untrusted code

Every execution is disposable, metered, and confined. Wire it into your agents through a single API.

Hardened isolation

Every job runs in a locked-down container with strict CPU, memory, PID and filesystem limits. gVisor isolation on sovereign tiers.

Zero retention

Prompts, code and outputs are destroyed when a run ends. Nothing is persisted beyond opt-in usage metering.

Agentic runtime

Multi-step agents that write and execute code, produce artifacts, and return a final answer — all through one endpoint.

Tiered compute

Developer to enterprise-sovereign tiers with predictable ceilings on cores, memory, concurrency and step budgets.

Single API surface

Execute raw code or run an agent with the same typed contract. Metering and readiness built in.

EU-hosted

Deployed on European infrastructure behind a hardened edge. Your workloads stay under European jurisdiction.

Your data never leaves Europe.

KEVLAR is engineered around a simple thesis: the safest place to run AI-generated code is a disposable sandbox you control, in a jurisdiction you trust. No prompts, no code, no artifacts are retained after a run completes.

Zero-retention execution — nothing survives the sandbox teardown.
European hosting with a single hardened TLS edge; no third-country transfers.
Per-tenant API keys, argon2-hashed, revocable in one click.
Transparent usage metering you can audit from the console.

Open the console

POST /v1/run

{
  "prompt": "Analyze sales.csv and plot revenue by month",
  "model": "enterprise-sovereign-model",
  "max_steps": 4
}

→ 200 OK
{
  "status": "succeeded",
  "answer_text": "Revenue peaked in November…",
  "artifacts": [ "revenue.png" ],
  "meta": { "retention": "none" }
}

Run your first agent in seconds.

The console ships with a live playground. Send a prompt, watch the agent reason, execute code, and produce downloadable artifacts.
