Answers, not asterisks.

ShipSilently is a feature flag and experimentation platform that decouples deployment from release. Wrap new code in a flag, deploy whenever you like, then turn the flag on for the users you choose — without redeploying.

Most teams have their first flag evaluating in under five minutes. Install an SDK, paste an API key, and call getFlag(). Our docs include copy-paste snippets for every supported language.

We currently ship official SDKs for JavaScript / TypeScript (shipsilently on npm) and Go (github.com/slewsoft/shipsilently-go). Python, Ruby, Java, and .NET SDKs are on the roadmap. Any language can use our REST API directly.

No. Once the SDK is installed, you can create flags, change targeting rules, and roll back from the dashboard with no redeploy required. Flag changes propagate to the edge in seconds.

Yes. The Hobby plan is free forever and includes 100,000 evaluations per month, up to 10 flags, and two environments — no credit card required. See the full breakdown on the pricing page.

Each call to getFlag() or evaluate() counts as one evaluation. Cached evaluations within the same request do not count toward your limit.

We never block traffic. You will receive a warning email and overages are billed at $0.01 per 10,000 additional evaluations. Your flags keep working.

Yes. Plan changes take effect immediately. Upgrades are prorated; downgrades take effect at the next billing cycle. There are no long-term contracts on Hobby or Pro.

Under 5 ms at p99. SDKs evaluate locally against rules cached at the edge, so flag checks do not add a network hop to your critical path.

Our SDKs ship with offline-first caching and configurable default values. If our service is unreachable, your application keeps serving the last known flag state — never an error.

We target 99.99% uptime on Pro and offer a contractual SLA on Enterprise. You can monitor real-time availability on our status page.

Rules are distributed to a global edge network so evaluations happen close to your users. No customer data is sent back to our servers during evaluation — only aggregated metrics.

Yes. ShipSilently is SOC 2 Type II certified. Reports are available under NDA for Enterprise customers — email hello@shipsilently.com.

SAML 2.0 SSO, SCIM provisioning, and role-based access control are available on the Enterprise plan. Pro accounts get email/password and Google SSO.

All data is encrypted in transit (TLS 1.3) and at rest (AES-256). We follow the principle of least privilege internally and audit every administrative action.

Yes. We offer a Data Processing Agreement (DPA) for all paid customers and support EU data residency on Enterprise. See our privacy policy for details.

Yes. We have migration guides for the most common platforms, and our team can help map your existing flags, segments, and rollout rules over for free.

Hobby users get community support via our docs and GitHub. Pro plans include email support with 24-hour response. Enterprise customers get a dedicated Slack channel and SLA-backed response times.

Yes. Enterprise customers get a dedicated implementation engineer who helps with rollout planning, SDK integration, and reviewer training. Get in touch to learn more.
