About jurniti

jurniti is a paid infrastructure service that assigns each AI agent its own Firecracker microVM with a KVM hardware boundary. The box stays on continuously, includes an in-browser terminal and persistent disk, and lets users bring their own model keys that remain inside the guest. Setup takes roughly three minutes after payment, with plans starting at $25 per month.

Review

jurniti targets a narrow problem: developers who want to run AI agents around the clock without keeping a personal machine awake or sharing kernel space with other users. The isolation model uses the same Firecracker primitive that powers AWS Lambda, which sets it apart from services that rely on shared Docker containers. This review examines what the shipped product actually does, who it serves, and where it falls short.

Key Features

• Dedicated Firecracker microVM per agent, not a shared container environment
• Bring-your-own-key architecture where model credentials stay inside the guest and the host cannot see them
• Always-on operation so agents keep working without a laptop staying powered and open
• In-browser terminal, persistent disk, and a subdomain delivered in about three minutes after purchase
• Compatible with Claude Code, Codex, Hermes, OpenClaw, and other upstream agents

Pricing and Value

Plans start at $25 per month. There is no free trial. A 30-day money-back guarantee applies to the first purchase, with refunds processed manually by the maker. The service requires users to supply their own model keys, so any API usage costs from those keys are separate and handled directly with the model provider.

Pros

• Hardware-level isolation via KVM means agent processes don't share a kernel with other tenants
• Model keys never leave the guest VM, which reduces exposure compared to services that inject keys as environment variables on shared hosts
• Short provisioning time-roughly three minutes from payment to a working box
• Persistent disk and always-on state let long-running agent tasks survive network interruptions and machine sleep cycles
• Straightforward refund policy with no automated denial loops

Cons

• No free trial means users must commit at least $25 before testing whether the environment fits their workflow
• Usage-based alerting or hard caps for runaway API calls are not yet part of the shipped product; the maker has not confirmed a kill-switch mechanism beyond the user monitoring their own model provider bill
• The service is not a good match for people who want a free agent playground or who don't already run agents with real credentials and need them active overnight

Who jurniti works for

This product fits developers who already run agents with production credentials and have hit the limit of keeping a laptop awake. The isolation story matters most to those handling client keys or sensitive workloads where shared-kernel setups feel like an unacceptable risk. If you don't need an always-on box or aren't comfortable managing your own model key billing, the $25 entry point and lack of a trial make it a harder sell.
