Pros & Cons
CertKit
Pros
Free Community tier makes it easy to evaluate the platform's core discovery and monitoring capabilities without cost.
Deployment via a single agent to a wide range of servers and network appliances, without needing ACME configured everywhere, simplifies rollout across heterogeneous infrastructure.
Certificate Transparency-based discovery surfaces forgotten or unauthorized certificates that manual tracking would likely miss.
Generous 90-day free trial on paid tiers with no credit card required lowers the barrier to a full evaluation.
Purpose-built and narrowly focused on certificate lifecycle management rather than being a small feature bolted onto a broader security suite.
Cons
A relatively new product, launched in 2024, with less of a long-term track record than established certificate lifecycle management vendors.
Small company (TrackJS LLC) behind the product means less scale of support and resources compared to larger enterprise security vendors.
Free and entry-level paid tiers cap certificate and agent counts fairly low (2 and 10 respectively), meaning larger organizations will need Business or Enterprise pricing quickly.
Enterprise pricing is custom and not published, requiring a sales conversation for large-scale or multi-tenant deployments.
As with any tool crawling Certificate Transparency logs, discovery is limited to publicly logged certificates and won't surface internal-only or private CA-issued certificates not logged publicly.
realstamp
Pros
Biometric Face ID check happens on-device via Secure Enclave, so raw biometric data never leaves the user's device
Stamps are anchored to Sigstore Rekor, giving independent, publicly auditable verification rather than a closed proprietary log
Generous free tier (10 stamps/month) makes it easy to try before committing to a paid plan
Wide integration surface: iOS/Android apps, WordPress plugin, browser extensions, embeddable SDK, and REST API
Cons
Free plan is capped at 10 stamps per month with only 30-day history, which may be limiting for active creators
Core verification relies on Face ID/Secure Enclave hardware, so support on non-Apple or older devices is unclear
As a newer entrant (patents still pending) it lacks the long track record of established e-signature or authenticity platforms
Higher-tier features like SSO, audit trails, and bulk verification API are gated behind the $99/month Business plan
Use Cases
CertKit
Preventing certificate-expiration outages — IT teams use CertKit's monitoring and automated renewal to eliminate the risk of a forgotten certificate expiring and taking down a production service unexpectedly.
Auditing an organization's full certificate footprint — Security teams use CertKit's Certificate Transparency-based discovery to build a complete inventory of every certificate issued for their domains, including ones issued outside official processes.
Managing certificates across multiple client environments — Managed service providers use CertKit's multi-tenant Enterprise tier to centrally track and automate certificate lifecycle management across many separate client infrastructures.
