Agent 37 review
Host persistent agents with browser tools, scheduled jobs, and a free starting plan.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Agent 37 offers managed hosting and a cloud API for running AI agents in persistent, isolated instances. It suits individuals exploring agents as well as builders provisioning instances for customer-facing products. Managed hosting comes with OpenClaw and Hermes, while the API can provision those agents or custom public Docker images, including images for LangChain and CrewAI. Templates are also available for Claude Code, Codex, OpenCode, and Grok.
The published plans start with Free, which supports one agent that sleeps when idle and requires your own API keys. Basic costs $3.99 per month and adds supported AI models, 1,000+ integrations, and $1 monthly AI credits. Plus is $9.99 per month and adds bundled model usage. Pro costs $29.99 per month, with a built-in Chromium browser, email/chat support, and $5 monthly AI credits. Max is $99.99 per month and includes a dedicated onboarding call, priority support, team management and roles, and $20 monthly AI credits. The separate Cloud API's smallest instance is listed at $4.76 per month at continuous runtime; it is metered per minute from a prepaid balance and has no seats.
Persistent state is a key distinction: files, memory, sessions, and tools carry across restarts, and cron-style jobs support scheduled work and recurring check-ins. A browser task board, web terminal, file browser, live desktop, and Server-Sent Events for streaming agent events add ways to monitor and connect agent activity. Kernel-enforced sandbox isolation is listed, along with SOC 2 compliance. Agent 37 is a fit for budget-conscious experimenters who want varied agents and persistent infrastructure; teams wanting a free always-on agent should look elsewhere, since the free agent sleeps when idle.
