How it works
From idea to live endpoint in minutes
Three steps. No DevOps. No Kubernetes manifests. Just your code, running everywhere.
Bring your tools
Push your MCP server, link your GitHub repo, or pick from 100+ pre-built integrations.
Host with Lnar
Each workload runs in an isolated gVisor sandbox on EKS. Real-time logs, traces, and metrics out of the box.
Call freely from any AI
Karpenter provisions GPU and CPU nodes on demand. Pay only for the seconds you use.
Why Lnar
The complete stack for agentic AI
Tool hosting, code execution, and observability — vertically integrated. Not a stitched-together pipeline.
Your agents
Lnar Platform
Cloud infra
Sub-second cold starts
Pre-warmed gVisor sandboxes mean your agent's first call lands in under a second — not 30.
MCP-native by design
Built on the Model Context Protocol from day one. Listed in the official MCP Registry.
Multi-tenant isolation
gVisor user-space kernel isolation. Workloads can't see each other — even on shared nodes.
Durable execution
Long-running agent loops survive restarts, crashes, and deployments — Temporal under the hood.
Built-in observability
Token usage, tool calls, latency, errors — streamed via ClickHouse. No setup required.
Global edge
Deploy to ap-northeast-1 and us-east-1 simultaneously. Route based on latency, residency, or cost.
Enterprise ready
Built for scale, security, and control
On-prem & private cloud
Run Lnar inside your VPC, your AWS account, or your own datacenter. Full data sovereignty.
RBAC & SSO
Role-based access with SAML, OIDC, and SCIM provisioning.
Audit logs
Tamper-evident logs of every API call, agent execution, and config change.
Compliance
SOC 2 Type II in progress. End-to-end encryption. Japan-resident data option.
Pre-built & custom integrations
Hundreds of MCP servers ready to connect, plus a custom connector SDK for internal systems.
Pricing
Simple, transparent pricing
Start free, scale as you grow. No surprise bills.
We're onboarding a select group of AI researchers, agent developers, and enterprise teams. Free during alpha — direct access to founders.
