Portal vs feature flag & observability (PostHog, LaunchDarkly): demo-session insights vs production analytics
February 23, 2026
PostHog, LaunchDarkly, and similar tools are built for production: feature flags, product analytics, A/B tests, and behavioral data for your live app and its users. Portal is built for user research and demo sessions: when you send a link so someone can try your product in a sandboxed browser, Portal gives you observability for that exact session—video, transcript, and click-level analytics. Think user research tool, not production analytics. Different moment, different use case.
How Portal lets you do it: different demo accounts per link
Portal lets you run different try-it experiences by having different demo accounts signed in per link (or per Portal). Each link can boot a different state—e.g. “enterprise” vs “startup” demo, or different feature flags—so you get the right experience for each audience. You get observability per session: who opened which link, what they did, video and transcript. That’s demo-session-level control and analytics, not production feature flags. PostHog and LaunchDarkly are about production flags and production analytics; Portal is about demo links and per-session visibility.
What PostHog and LaunchDarkly do
They help you control what users see (feature flags, experiments) and measure how they behave in your production app. You get funnels, session replay, events, and flags—all in the context of “my live product and its users.” They’re not built for “I sent a link to a prospect; I want to see exactly what they did in that temporary try-it session.”
What Portal does
Portal turns a real browser state into a link. When someone opens it, they get a live, isolated session—your real product in a chosen state, with guardrails. You get built-in analytics for that session: video, transcript, and click-level data. So you can see where they hesitated, what they clicked, what they asked the AI—perfect for user research, feedback on new features, or replacing first demo calls without losing visibility. As we’ve put it: Get user feedback on new features with built-in analytics. That’s observability inside the try-it moment, not replacement for your production analytics stack.
Key differences
| Dimension | Portal | PostHog / LaunchDarkly |
|---|---|---|
| Primary use | Observability for shared demo/try-it sessions | Feature flags + analytics for production app |
| Moment | “Someone opened my Portal link and tried my product” | “Users are using my live product” |
| What you get | Video, transcript, click-level data per Portal session | Events, funnels, replay, flags for production traffic |
| Guardrails | Built-in for the demo session (URLs, selectors, APIs, time limit) | N/A (they don’t run the session) |
| Replaces PostHog/LaunchDarkly? | No—different layer | N/A |
When to choose Portal
- You want to send a link so someone can try your product (or a new feature) and you want video, transcript, and click-level visibility into what they did.
- You’re doing user research, feedback on new features, or replacing first demo calls—and you want that try-it moment instrumented without wiring up a separate replay/analytics flow for one-off sessions.
- You want first-party behavioral insights for demo and try-it sessions—world-class analytics for the “they tried it” moment.
When to use PostHog / LaunchDarkly
- You need feature flags, experiments, and product analytics for your production app and its users.
- You’re not looking for a “share a link, they try it, we see everything” product—you’re looking for control and measurement of your live product.
Summary
PostHog and LaunchDarkly are for production—flags and analytics for your live app. Portal is for demo and try-it sessions—observability when you share a link so someone can try your product. Use both: production analytics with PostHog/LaunchDarkly, demo-session observability with Portal.
