I'm Abdalla, and I built Marsad because shipping a Next.js web app and an Expo mobile app meant paying three vendors to answer one question. An error tracker told me something broke. An analytics tool told me traffic dropped. Neither told me they were the same route. At 2am, mid-incident, I was correlating tabs by hand. Marsad is one SDK. One init() call captures unhandled errors, network requests, sessions and crash-free rate, Core Web Vitals, performance traces, and page views — for the browser, Node, and React Native. Errors arrive grouped into ranked issues with source-mapped stacks and the breadcrumbs that led there. Traffic lands next to them, on the same screen. The analytics is cookieless. Unique visitors come from a daily-rotating hash computed server-side, so nothing is stored on anyone's device and there's no consent banner to build. The honest cost of that: unique visitors are a daily figure, because by design I no longer hold anything that links Monday's visitor to Thursday's. Cross-day retention cohorts aren't possible, and I'd rather say so than quietly not have them. What it doesn't do yet: native mobile crash capture (iOS signals, Android JVM crashes and ANRs). React Native support covers JS-thread errors today. No session replay, no profiling. If those decide it for you, use Sentry — they're genuinely better at that, and I'd rather you not sign up and find an empty dashboard. Pricing is flat per organization, never per seat. Free gives you 10,000 page views and 5,000 errors a month with no card. Solo is $9, Team is $29. Going over your plan pauses ingestion with a three-day grace period and reminders instead of billing you — a bad deploy that fires a million errors overnight should be a notification, not an invoice. The SDK is about 18 kB gzipped with zero runtime dependencies. You don't need an account to judge it: the live demo is a fully populated dashboard with issues, traces, analytics, logs, sessions and alerts. https://www.marsad.space/demo I'd genuinely like to know what's missing for your stack — I'm here all day.
