• Replaces four or five separate subscriptions with one bill and one SDK.
• Free tier is large enough for real production use at startup scale.
• Open source with a credible self-hosting path.

• Full data sovereignty — recordings stay inside your infrastructure.
• Developer-focused feature set comparable to LogRocket.
• No volume-based pricing when self-hosted.

• Individual modules are less deep than category specialists.
• Self-hosting at scale is a serious infrastructure undertaking.
• The product surface changes fast, which means occasional churn.

• Self-hosting session replay is a non-trivial operational commitment, including storage.
• Smaller community and fewer integrations than the commercial tools.
• Analytics and funnel features are thinner.

Startups and scale-ups consolidating analytics, replay and flags into one platform.

Privacy-constrained or high-volume teams that cannot use a hosted replay vendor.
