USCIS forms are painful. The official PDFs are XFA-based - broken in most browsers. Third-party tools charge money or require an account just to get started.

Fillvisa is different: it runs entirely in your browser, saves your progress to localStorage, and generates a real fillable AcroForm PDF - ready to print and submit. No account. No server. Your data never leaves your device.

If you or someone you know is navigating the immigration process, I'd love for you to try it and tell me what's missing.

Features:

Auto-save: Your progress is saved automatically, allowing you to pause and resume without losing any data.

Local-only Storage: All information is stored on your device, ensuring complete privacy and security.

Automatic Form Filling: Fillvisa provides perfectly formatted, ready-to-download USCIS PDFs without the need for manual edits or additional tools.

Built-in Signature Pad: Sign forms directly in your browser, eliminating the need for printing or scanning.

Smart Form Checks: Built-in validation ensures that mistakes are caught instantly, streamlining the form completion process.

Fillvisa is designed to make immigration form preparation accessible and stress-free, allowing users to focus on their new life rather than paperwork.

Whether you're applying for a visa, renewing a green card, or changing your address, Fillvisa simplifies the process with its user-friendly interface and comprehensive features.

    CodeLighthouse provides real-time error tracking and monitoring for applications, allowing developers to quickly identify and respond to issues as they occur in production environments.
  • Easy integration
    The platform offers straightforward integration with popular programming languages and frameworks, making it relatively simple for development teams to get started with minimal setup effort.
  • Actionable error insights
    CodeLighthouse provides detailed error reports with contextual information, stack traces, and relevant metadata that help developers quickly diagnose and fix issues rather than just alerting them to problems.

  • Affordable for small teams
    CodeLighthouse positions itself as a cost-effective solution for smaller development teams and startups that need error monitoring without the premium price tag of larger enterprise-focused competitors.

Possible disadvantages of CodeLighthouse

  • Limited market presence
    CodeLighthouse is a relatively small and lesser-known player in the error monitoring space, which means fewer community resources, third-party integrations, and peer support compared to established tools like Sentry or Datadog.
  • Smaller ecosystem of integrations
    Compared to more established competitors, CodeLighthouse may offer fewer out-of-the-box integrations with third-party tools, CI/CD pipelines, and communication platforms, potentially requiring additional custom work.
  • Limited language and framework support
    As a smaller platform, CodeLighthouse may not support as wide a range of programming languages and frameworks as larger, more mature error monitoring solutions.
  • Uncertain long-term viability
    Being a smaller company, there may be concerns about long-term sustainability and continued development, which could be a risk factor for teams making a long-term tooling commitment.
  • Fewer advanced features
    CodeLighthouse may lack some of the more advanced features offered by larger competitors, such as sophisticated performance monitoring, AI-powered error grouping, or extensive analytics and reporting capabilities.

Analysis of Filllvisa

Overall verdict

  • I don't have verified, up-to-date information about Fillvisa (fillvisa.com), so I can't confirm whether it is a good or reputable service. Visa-related and immigration-assistance websites vary widely in legitimacy and quality, so it's important to verify independently before using or paying for such a service.

Why this product is good

  • I do not have reliable or current data on this specific website's reputation, ownership, or user reviews.
  • Visa-assistance services can range from legitimate document-preparation help to scams, so claims should not be taken at face value without verification.
  • No independent, verifiable reviews or regulatory information about Fillvisa were available to assess its credibility.

Recommended for

  • Not recommended to rely solely on this responseโ€”users should independently verify the company's legitimacy through official government visa resources, consumer review sites (like Trustpilot or BBB), and check for verifiable contact information, business registration, and user testimonials before using the service.
  • Individuals seeking visa help should generally prioritize official embassy/consulate websites or licensed immigration attorneys over third-party services with unverified track records.

Analysis of CodeLighthouse

Overall verdict

  • CodeLighthouse appears to be a niche developer/monitoring tool, but there is limited independent, verifiable information available publicly to fully confirm its reliability, feature depth, or long-term support. Users interested in it should proceed with a trial or proof-of-concept before committing, and verify current reviews, uptime guarantees, and support responsiveness directly with the vendor.

Why this product is good

  • May offer a focused feature set for a specific developer or monitoring niche, which can simplify adoption compared to bloated enterprise tools.
  • Likely provides a straightforward pricing or onboarding process typical of smaller SaaS tools.
  • Could offer more personalized customer support due to smaller scale compared to large competitors.
  • Potential quick setup and lightweight integration for small teams or individual developers.

Recommended for

  • Small development teams or solo developers looking for a lightweight, specialized tool.
  • Startups wanting to test a niche solution without heavy long-term commitment.
  • Users who prioritize simplicity and quick setup over extensive enterprise features.
  • Teams willing to directly vet a smaller vendor's reliability and roadmap before scaling usage.

Questions & Answers

As answered by people managing Filllvisa and CodeLighthouse.

What's the story behind your product?

Filllvisa's answer

Built by Junaid, a founder with a personal connection to the immigration experience. The core frustration was that existing free tools were either low-quality fillable PDFs, server-side tools that harvested user data, or paywalled SaaS products. Fillvisa was built to give immigrants the tool they actually deserve - professional-grade, private, and genuinely free.

How would you describe the primary audience of your product?

Filllvisa's answer

Immigrants navigating the U.S. naturalization or adjustment-of-status process on their own - people filing forms like the N-400 without legal representation, often cost-sensitive, frequently non-native English speakers, and deeply privacy-conscious about where their personal information goes.

Why should a person choose your product over its competitors?

Filllvisa's answer

It's free with zero friction - no signup, no paywall, no upsell nag. Your data stays on your device. The output is a properly filled, submission-ready PDF, not a printable web form. For immigrants who can't afford an attorney and don't trust third-party servers with sensitive personal data, that combination is hard to beat.

What makes your product unique?

Filllvisa's answer

Fillvisa is 100% client-side - no account, no server, no data ever leaves the browser. It runs entirely on localStorage, generates real AcroForm PDFs via pdf-lib, and embeds structured JSON metadata directly into the PDF so forms can be re-imported and resumed later.

No other free USCIS form tool offers that round-trip fidelity.

Which are the primary technologies used for building your product?

Filllvisa's answer

HTML, vanilla JavaScript, pdf-lib (PDF generation), localStorage (persistence), and a per-page -map.js validation config architecture. No frameworks, no backend, no database. Fully static and deployable as a CDN asset.

Who are some of the biggest customers of your product?

Filllvisa's answer

As a free consumer tool, Fillvisa doesn't have "customers" in the traditional sense. It has users - immigrants filing USCIS forms independently. There are no named enterprise accounts or notable client logos to list.

  • Ask HN: What Are You Working On? (May 2026)
    Fillvisa โ€“ https://fillvisa.com USCIS immigration forms are still distributed as XFA PDFs - a deprecated Adobe format that modern browsers and PDF readers can't render or fill. Immigrants download them, get a blank white page, and give up. I built a client-side tool that converts those XFA forms into fillable web forms - no account, no upload, everything runs in the browser. That's the free tier. The paid side... - Source: Hacker News / 3 months ago
