Self-Hosted Session Replay for Developers

Services like Fullstory and Logrocket are expensive and send user data to third parties. This self-hosted alternative lets developers capture and replay browser sessions for debugging using rrweb, keeping all data on their own infrastructure. Target: privacy-conscious startups and enterprises.

GDPR enforcement, SOC 2 requirements, and growing enterprise sensitivity around third-party data processors have made "no data leaves your infrastructure" a real procurement requirement, not just a preference. OpenReplay exists and is the obvious incumbent here — it's open source, actively maintained, and already does exactly this with rrweb under the hood, which makes differentiation genuinely hard unless you're targeting a specific vertical or offering managed self-hosted deployment as a service. The $2k–10k/mo band is plausible only through a hosted-on-your-infra model with support contracts, since pure open source generates nothing; the ceiling is low because enterprises that care enough to self-host often have engineers who'll just deploy OpenReplay themselves. The most likely failure mode is that OpenReplay already occupies this space well enough that there's no wedge left — building a better version of something that's already free and good is a distribution problem, not a technical one.
