PostHog vs OpenCTI
A side-by-side editorial comparison of PostHog and OpenCTI — release velocity, themes, recent moves, and the top alternatives to consider.
PostHog vs OpenCTI: at a glance
What is PostHog?
PostHog is filling in Logs and the mobile SDKs while quietly growing a support product.
PostHog ships weekly, and this week's batch is spread across four teams rather than concentrated in one product. Logs gets attribute filtering and a React Native capture path; the iOS SDK gains rage-click detection and a session-replay duration floor; Conversations picks up GitHub issues as an inbound support channel. Individually these are small, and the weekly digest bundles them into a single roundup entry.
What is OpenCTI?
OpenCTI ships FIPS-validated base images and a new vulnerability data model, targeting enterprise and government deployments.
OpenCTI is in a high-cadence operational hardening phase, releasing every 2–4 days. The recent window shows three parallel tracks: enterprise compliance (FIPS 140-3 validated Python/Node base image), platform-wide design unification (Filigran Design System v1 rollout), and data model expansion (new vulnerability module, score fields on threat actor and malware entities). The AI chatbot 'Ask Ariane' received multiple crash fixes, and a prior release added human-in-the-loop tool approval — signs that the AI analysis layer is maturing from experimental to production-grade.

PostHog
0.0ANALYTICS
PostHog is filling in Logs and the mobile SDKs while quietly growing a support product.
◆ Current state
PostHog ships weekly, and this week's batch is spread across four teams rather than concentrated in one product. Logs gets attribute filtering and a React Native capture path; the iOS SDK gains rage-click detection and a session-replay duration floor; Conversations picks up GitHub issues as an inbound support channel. Individually these are small, and the weekly digest bundles them into a single roundup entry.
◆ Where it's heading
Two build-outs are running in parallel. The observability side — Logs plus the mobile SDKs — is being brought up to parity with what PostHog already offers on web, which is what makes the platform credible for mobile teams rather than web analytics with an SDK attached. The Conversations work is the more interesting thread: adding support channels moves PostHog past measuring users toward handling them, and it is being built out in the same incremental weekly rhythm as everything else.
◆ Prediction
Expect Logs and the mobile SDKs to keep receiving parity features on the weekly cadence, and expect Conversations to add further inbound channels beyond GitHub issues. The entries do not show whether Conversations is being positioned as a standalone product or a feature of the existing suite.
OpenCTI
6.3ANALYTICS
OpenCTI ships FIPS-validated base images and a new vulnerability data model, targeting enterprise and government deployments.
◆ Current state
OpenCTI is in a high-cadence operational hardening phase, releasing every 2–4 days. The recent window shows three parallel tracks: enterprise compliance (FIPS 140-3 validated Python/Node base image), platform-wide design unification (Filigran Design System v1 rollout), and data model expansion (new vulnerability module, score fields on threat actor and malware entities). The AI chatbot 'Ask Ariane' received multiple crash fixes, and a prior release added human-in-the-loop tool approval — signs that the AI analysis layer is maturing from experimental to production-grade.
◆ Where it's heading
The combination of FIPS compliance, accessibility hardening, and enterprise-grade session key management signals a deliberate push toward government and regulated-sector deployments. The vulnerability module and inference rules that propagate vulnerability data across the knowledge graph suggest OpenCTI is building toward a more automated threat-correlation engine rather than just a data store.
◆ Prediction
Ask Ariane's human-in-the-loop approval will likely move from opt-in to default as the team gains confidence in the AI tool set. Watch for more inference rules that auto-link threat entities, and for the vulnerability module to grow into a first-class surface with dedicated views and reporting.
