Clearhavn is the calm, cross-platform alternative to MyCourtClerk, Alimentor 2, and the spreadsheet you've been keeping. Built specifically for family-law cases โ€” custody, support, protective orders โ€” not generic case management.

Where Alimentor 2 is iPhone-only and a one-time purchase, Clearhavn works on any device and syncs across web, iOS, and Android. Where MyCourtClerk pushes a heavier interface, Clearhavn stays calm and focused. Where a spreadsheet stops working at 50 events, Clearhavn surfaces patterns automatically.

Key features: โ€ข Event log with severity, location, and per-event evidence attachments โ€ข Issue tags (custody schedule, communication, school, medical) with pattern detection โ€ข Calendar of upcoming hearings, deadlines, exchanges โ€ข Witnesses, parties, children, and court orders in one workspace โ€ข Court-ready PDF chronology and full case-packet export (Pro) โ€ข Read-only attorney sharing โ€” invite by email, revoke anytime (Pro)

Free for one case. Pro is $12/month. Cancel anytime.

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

Analysis of Clearhavn

Overall verdict

  • I don't have reliable, verified information about Clearhavn (clearhavn.com) in my training data, so I can't confirm whether it's a legitimate or high-quality product/service. Before trusting or purchasing from this site, I'd recommend doing independent verification.

Why this product is good

  • I have no confirmed data on this specific domain's reputation, business practices, or user reviews
  • Unfamiliar or newer domains can sometimes be low-quality, scams, or simply lack an established track record
  • Without verified information, making a positive or negative claim would be speculative and potentially misleading

Recommended for

  • Not applicable - insufficient verified information to recommend this for any specific use case
  • If you're considering this site, check independent review platforms like Trustpilot, BBB, or Reddit
  • Verify company registration, contact information, and return/refund policies before purchasing
  • Look for secure payment indicators (HTTPS, trusted payment processors) and read recent customer reviews

Analysis of React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment

Questions & Answers

As answered by people managing Clearhavn and React Engine.

What makes your product unique?

Clearhavn's answer

Clearhavn is built specifically for family-law cases โ€” custody, support, protective orders โ€” not generic case management.

  • Cross-platform: where Alimentor 2 is iPhone-only and a one-time purchase, Clearhavn syncs across web and iOS (Android in beta).
  • Calm UX: where MyCourtClerk's interface is heavier, Clearhavn stays focused on documentation.
  • Pattern detection: where a spreadsheet stops working at 50 events, Clearhavn tags events by issue and surfaces recurring patterns automatically โ€” eleven late pickups become visible as a pattern, not just three you happen to remember.

Why should a person choose your product over its competitors?

Clearhavn's answer

If you're preparing for a custody hearing or working with an attorney, you spend more time documenting than scheduling โ€” and existing tools either focus on co-parent communication (OurFamilyWizard, TalkingParents) or scheduling (Custody X Change). Clearhavn focuses on the documentation layer: events with linked evidence, witnesses, court orders, and a one-click court-ready chronology PDF.

  • Price: $12/month vs $40/month for MyCourtClerk.
  • Platform: web + iOS + Android, not iPhone-only like Alimentor 2.
  • Free plan: covers one case forever, so you can try the full documentation flow before paying anything.

How would you describe the primary audience of your product?

Clearhavn's answer

Primary audience: self-represented parents preparing for custody, support, or protective-order hearings โ€” people who need a court-ready record but can't justify $40-100/month per parent.

Secondary audience: parents working with a family-law attorney who want to show up to meetings organized instead of emailing 47 unsorted screenshots. Pro plans include read-only attorney sharing so counsel can review the case on their own time.

What's the story behind your product?

Clearhavn's answer

Ryan Marshall built Clearhavn after going through his own family-law case and realizing the existing tools fell into three buckets: spreadsheets that fell apart at 50 events, iPhone-only apps stuck in a one-time-purchase model from a decade ago, or enterprise legal software priced for law firms. There wasn't a calm, modern, cross-platform tool built for the parent โ€” just for the lawyer or the time tracker.

Clearhavn is what he needed at 11 PM on a Sunday trying to assemble a chronology before a Wednesday hearing. It's now used by self-represented parents and clients of family-law attorneys to organize their case into a clear, court-ready record.

Which are the primary technologies used for building your product?

Clearhavn's answer

  • Web: Next.js 15 (App Router) with TypeScript, deployed on Vercel with Cloudflare DNS.
  • Mobile: native iOS app built with Expo (React Native), sharing a custom HMAC-signed bearer-token API with the web backend.
  • Data: Neon Postgres with Drizzle ORM. Cloudflare R2 for evidence file storage.
  • Auth & billing: Auth.js v5 for web sessions. Stripe for subscriptions.
  • Infrastructure: Resend + React Email for transactional and onboarding mail, Sentry for error monitoring, Plausible for cookieless analytics, Cloudflare Turnstile for signup CAPTCHA.
