Secure, disposable cloud sandboxes that let AI agents safely execute generated code without touching real production systems.
Best alternatives to Maritime in 2026
If you're building a product where every customer gets their own AI agent — one that needs to remember files, keep a browser session open, or keep a background process running — renting a full server per customer gets expensive fast. Maritime's answer is a dedicated but very cheap virtual machine per agent that automatically falls asleep within about a second when it's not being used, and wakes up just as fast when it is. Maritime is a cloud infrastructure platform purpose-built for AI agent deployment. One command spins up an isolated micro-VM per agent, supporting frameworks like OpenClaw, Hermes, ZeroClaw, CrewAI and LangGraph, with CLI, TypeScript and Python SDKs and webhook notifications for lifecycle events. Pricing starts at a free tier (3 agents) and scales through Starter ($20/month, 20 agents), Growth ($100/month, 100 agents) and Scale ($500/month, 500 agents) plans, working out to roughly $1 per agent per month at volume, with extra RAM and SSD billed separately. It targets three groups: individual developers experimenting with agents, startups that sell agents to their own customers and need per-customer isolation, and enterprises wanting self-hosted or on-premises deployment.
