Pricing
Free for one. Affordable for teams.
Self-host the entire stack for free, forever, on your own hardware. Pay only when you want us to operate the parts that need infrastructure: hosted SMS, mobile push, cloud receipt sync. Billing is via Paddle (handles tax + invoicing globally).
Self-host. BYO keys. No vendor lock-in. The free tier is the whole product, not a trial. Upstream LLM keys are forwarded once and never persisted. The protocol is open; the receipts verify offline with any Ed25519 library. Switching costs to other governance vendors are by design close to zero, the opposite of an enterprise control-tower license. vs ServiceNow →

Common questions
What does “100 requests / day” on Free actually mean?
A request is any call to /v1/messages or /v1/chat/completions on a hosted gateway. Self-hosted gateways have no limit. The cap is to keep the hosted free tier sustainable; you can run an unlimited local gateway forever.
What if I outgrow the limit mid-day?
We don't cut you off. We email and ask if you want to upgrade. If you say no, we throttle gracefully starting the next day.
What about LLM costs? Are those included?
No, you pay your LLM provider directly. We're middleware. Your Anthropic / OpenAI bill is separate. Most customers see ~30–60% reduction in their provider bill via SynOI's cache + body-shrink.
Who handles billing?
Paddle. They're our merchant-of-record, which means they handle VAT, sales tax, invoicing, and chargebacks globally. You'll see “Paddle.com” on your statement.
Can I self-host the gateway?
Yes. The Gateway is the same software whether you run it on your laptop, your office server, or we host it for you. License key activates the same features either way.
How do I cancel?
One click in the portal at app.synoi.systems → Billing. Cancellation takes effect at the end of the current period. You keep access until then.
Enterprise: what's actually different?
On-prem deployment, SSO/SAML, signed BAAs and DPAs, SOC 2 Type II evidence, custom Policy Packs, SLA, and a person on the other end of email. Annual contract. Sales-led.
What's the difference between Gateway tiers and Verified Publisher tiers?
Different buyers. Gateway tiers protect you when you install packages (developers, agent operators, ops teams). Verified Publisher tiers protect packages you publish (open-source maintainers, plugin businesses). Most engineering organizations buy from both sides because they do both. Pricing is independent: a 5-person studio publishing one internal package and consuming many would pay Studio (publisher, $99/mo) plus Team (gateway, $99/seat × 5 = $495/mo) = $594/mo total.
My OSS package has 80,000 weekly downloads, close to the 100K free threshold. Do I pay?
Email supplychain@synoi.systems and tell us. The 100K threshold is a guideline, not a fence. Critical infrastructure with lower download counts (security-sensitive packages, ecosystem foundations, niche-but-load-bearing) is free at our discretion.
Can I just use the free CLI to check packages?
Yes. npx @synoi/scg-inspect <package>@<version>runs the full divergence taxonomy against any npm package: no signup, no install, no infrastructure. Use it ad hoc whenever you're about to depend on something new. The CLI is part of the free tier and stays free forever.
How does Verified Publisher actually stop an Axios-style attack?
When you opt in to Verified Publisher, your npm publishgoes through a wrapper that requires out-of-band approval on a second device before the release ships. A stolen long-lived token alone can't complete the publish: the attacker would need to also compromise your phone, your hardware key, or whichever HITL channel you've configured. That's the cost asymmetry that defeats opportunistic credential theft.
