Cheapest for you: Spot
On-Demand ($6.08/mo) is cheaper than the $25flat plan at this usage — you’re below the ~500 h/mo crossover.
On-Demand beats the $25 flat plan below ~500 h/mo; above that, the flat plan wins. Spot always undercuts On-Demand.

On every plan
What's included before you spend a cent.
The platform doesn't change between tiers. Only the box does.
BYOK for every model provider
OpenRouter, OpenAI, Anthropic, Nous Portal — paste your key into the VM once and your tokens never leave it. We don't proxy, don't see counts, don't mark up.
Public TLS subdomain
<you>.jurniti.com is auto-provisioned and certificate-managed. Plug it into your agent's webhook, dashboard, or chat bridge.
Persistent /persist volume
Skills, memory, conversation history, plugin state — anything you write under /persist survives restart, resize, and snapshot.
30-day money-back guarantee
Cancel your first plan within 30 days for a full refund, no forms, no support gauntlet. The guarantee covers your first subscription and ends once you expand. After that, cancel anytime — your VM keeps running to the end of the period you've paid for, then simply doesn't renew.
Template + fork
Snapshot any VM into a template (private or public). Fork a public template to spin up a configured agent in one Checkout.
What you won't see on the bill
The costs we deliberately don't charge.
Most managed-agent billing pages are minefields. This one isn't.
Token markup
Your model bill goes to your model provider, not to us. BYOK is non-negotiable; we never insert ourselves into the largest line item on your bill.
Per-request fees
No usage metering. No per-invocation charge. Run your agent into the ground at no incremental cost.
Idle-time charges
The VM is yours 24/7. We don't bill differently when it's busy and we don't auto-suspend it for being quiet.
Egress overages
Bandwidth is generous (100/200/500 Mbit/s burst). We don't meter outgoing bytes.
Snapshot or fork fees
Public templates are unlimited and free forever, and forking one into a new VM is a normal Checkout — no snapshot fee, no fork fee. Only private-template storage is paid, via the count-based Templates plan (5/10/20/50 slots at $5/$9/$17/$29 a month).
Onboarding / setup
Auto-provision runs the moment Stripe confirms the payment. No founder-led demo, no setup tax, no onboarding call required to get root.
FAQ
Questions you should ask before paying anyone.
- How much does managed agent hosting cost on jurniti?
- Starter is $25/month or $250/year (2 months free). Pro is $49/month or $490/year. Max is $99/month or $990/year. Every plan is a flat fee per VM with no token markup, no metered surprises, and a 30-day money-back guarantee.
- Is there a free trial or free tier?
- No. Spinning up a real Firecracker microVM costs us roughly $0.30–$1.20 a day depending on plan, so a free trial would mean burning cash on browsers who never convert. Instead, every plan ships with a 30-day money-back guarantee on your first plan: cancel within 30 days for a full refund, no questions asked. The guarantee applies to your first subscription and ends once you expand (add a second VM, upgrade, or buy a Templates plan) — by then you've decided we're worth it. You can always cancel anytime; outside the guarantee window, cancelling stops the next renewal and your VM keeps running until the end of the period you've already paid for.
- Can I pay by the hour instead of a flat monthly fee?
- Yes. On-Demand is $0.05/hour and is never interrupted while running — it starts in seconds when warm capacity is available, otherwise it's queued and you'll be emailed when it starts. Spot is $0.025/hour and can be interrupted: AWS reclaims can lose up to the last ~10 minutes of unsynced work; jurniti-initiated pauses lose nothing — it pauses gracefully and restores automatically. Both run on prepaid credits ($10 minimum top-up, card charged only when you top up) and are metered per second while running, so stopping the agent stops the spend. Running 24/7 ≈ $36.50/mo on On-Demand, so the $25/mo flat plan is cheaper for always-on.
- Why a microVM instead of a Docker container?
- Docker shares one Linux kernel across every tenant on the box. A kernel bug or container escape in your neighbor's workload can become your problem. Firecracker spins up a real KVM-backed virtual machine per tenant — the same primitive AWS uses to isolate Lambda invocations. Hardware-enforced boundaries, not namespace tricks.
- What does BYOK mean in practice?
- Bring Your Own Key. Your OpenRouter, OpenAI, Anthropic, or Nous Portal key is pasted once into your VM's environment file and never leaves it. We don't proxy your model traffic, don't see your token counts, and don't mark up your spend. You pay your model provider direct — typically the largest line item on your bill, and one we have no business inserting ourselves into.
- Can I run multiple agents on one VM?
- No — each agent gets its own microVM and its own subscription. Hermes + OpenClaw + Pi at Starter is 3 × $25/month. We don't bundle harnesses inside one VM because it would break the per-tenant hardware isolation boundary and starve resources at the Starter tier. Each VM is billed independently, so you can mix monthly and annual across agents.
- Where do my VMs run?
- us-west-2 today, on AWS EC2 nested-virtualization hosts — one density-sliced host per region. Additional regions land when committed regional MRR clears the cost of a second box; we rent capacity ahead of demand only when the math works, so we never have to raise prices because of idle infrastructure.
- What happens to my data if I cancel?
- Your persist volume (the /dev/vdb mount that holds your skills, memory, and agent state) stays live until the end of your paid period. Before deletion you can fork it into a private template — that creates a snapshot you can restore into a fresh VM later or share publicly. After deletion we keep no backups; the boundary is real.
- Can I switch plans?
- Yes. Upgrade or downgrade from the dashboard; Stripe pro-rates the difference. Resizing a VM happens at the next restart (a few seconds of downtime). Your persist volume comes with you across the resize.
- Do you charge for templates or forks?
- Public templates are unlimited and free forever — that's the growth loop. Private templates use a count-based Templates plan: 4 tiers (t5/t10/t20/t50 = 5/10/20/50 private slots) at $5/$9/$17/$29 per month, billed as one SubscriptionItem on your oldest active sub. There is no free private tier. Forking a public template into a new VM is a normal Stripe Checkout — same plan price, no fork fee.
