Cosmik

About this app

Cosmik is a beautifully designed web app that lets you track the ISS, Starlink, and over 20,000 satellites in real-time 3D, all from your browser—no app, no login required. It’s like having a personal planetarium that shows you exactly what’s flying overhead right now. You can set free push or email alerts so you never miss a satellite pass, rocket launch, or Starlink train. The launch news hub covers every mission in seven languages, and there’s even a handy ISS pass calculator for over 550 cities. Whether you’re a seasoned stargazer or just curious about that bright light in the sky, Cosmik makes space feel immediate and accessible. I love dragging the 3D globe to see where satellites are right this second—it’s addictive and educational. The best part? It’s completely free, with optional Pro for removing ads and unlocking extra features.

Key features

1Real-time 3D tracking of 20,000+ satellites including ISS and Starlink from browser
2Free push/email alerts for passes, launches, and Starlink trains
3Launch news hub in 7 languages plus ISS pass calculator for 550+ cities

Target customer profile

Drawn from the product itself, not from a survey.

Demographic

Space enthusiasts and amateur astronomers

Pain points

Hard to know when and where to look for satellites or the ISS; existing tools are too complex or require downloads.

Primary needs

Simple, real-time tracking with alerts; no login or app installation.

Demographic

Educators and science communicators

Pain points

Need engaging, visual tools to explain satellite orbits and space missions to students; limited time to prepare.

Primary needs

Interactive 3D visualization, free access, and multilingual news for classroom use.

Demographic

Tech-savvy hobbyists and early adopters

Pain points

Want to track specific satellites or launches, but lack an intuitive interface with push notifications.

Primary needs

Custom alerts for specific passes or launches, real-time data, and a modern UI.

Scout Review

Written by AI from measured evidence, scored out of 100.

Cosmik offers an elegant, no-friction way to visualize 20,000+ satellites and launches in 3D directly in the browser. Strong design language and practical features like city-specific ISS passes and alerts make it accessible, while measured performance and early-stage traction highlight areas still maturing. It sits ahead of peers on visual polish and simplicity but behind on speed and established community.

Measure by measure

Usability

Zero-friction browser access, instant filters, free alerts, and 550-city ISS calculator; multilingual news adds reach for educators.

Design

Polished dark-space theme with glowing accents and clear modal hierarchy; minor padding and placeholder text issues on live site.

Speed

Mobile Lighthouse 29/100 with slow LCP and high TBT; real-time 3D from official feeds works but initial load feels heavy.

Security

Strong core headers (HTTPS, HSTS, SPF/DMARC) and 9/12 checklist; missing CSP and no public audits or compliance claims.

Accessibility

Perfect 100/100 Lighthouse score plus built-in 7-language support; responsive 3D view with clear toggles.

Growth

Brand-new domain (June 2026) with only Twitter presence; zero reviews, stars, or community signals yet.

Improvement areas

Mobile performance (29/100 Lighthouse) and slow initial 3D load times
Missing CSP header and public security/compliance documentation
Zero user reviews or community traction after one month live

Design & Usability

Cosmik delivers a visually cohesive dark-space interface with intuitive 3D globe controls and instant credibility from live object counts. The sidebar and filter panel keep interactions lightweight while the Launch Center modal provides clear countdowns and actions. Usability shines through zero-login browser access and built-in alerts plus multilingual news, though the product is still early so documentation remains minimal. The combination makes satellite tracking feel immediate for hobbyists and educators alike.

Speed & Security

Performance is the clear weak spot with a 29/100 mobile Lighthouse score driven by slow LCP and blocking time, though the core real-time data feeds function once loaded. Security posture is respectable for a new project—solid headers including HSTS and DMARC with no major TLS issues—but lacks CSP and any third-party audits. For a free, public visualization tool these trade-offs are understandable at one month old.

Accessibility & Growth

Accessibility benefits from a perfect automated score and native multi-language support, positioning it well for classroom use. Growth is predictably low given the June 2026 domain registration and absence of reviews or community metrics; trajectory depends on continued updates and word-of-mouth. Early indicators like embeddable widgets and Telegram alerts show intent to expand reach.

Conclusion

For space enthusiasts tired of clunky trackers, Cosmik is worth bookmarking now—especially once the placeholder copy and load times improve.
