About code-prettify and Filllvisa

In their own words, as submitted to SaaSHub.

Filllvisa

No description of code-prettify yet.

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 -...

Features and specs

What each product offers, as listed by its team.

code-prettify 4 features
Filllvisa 5 features
  • Easy to Integrate
    Code-prettify is simple to integrate into web projects. It uses plain JavaScript and works by adding a single script tag to your HTML, which makes it easy to set up.
  • Language Support
    The library supports a wide range of programming languages out of the box, which makes it versatile for various types of code highlighting without needing additional plugins.
  • Lightweight
    Compared to some other syntax highlighters, code-prettify has a relatively small footprint, which helps in maintaining fast loading times for web pages.
  • Browser Compatibility
    It is compatible with most modern and older browsers, ensuring consistent syntax highlighting across different client environments.

Possible disadvantages

  • Archived Status
    The repository is archived, meaning it is no longer actively maintained by Google. This could pose issues with future compatibility or bug fixes.
  • Customization Limitations
    While it provides a decent level of default styling, customization options are limited compared to some other syntax highlighters that offer more theming flexibility.
  • Lack of Recent Updates
    Being an archived project, it doesn't receive updates or improvements, missing out on newer features or optimizations available in currently maintained libraries.
  • Community Support
    As the project is no longer active, community support may be limited, making it potentially challenging to get help or find resources for troubleshooting issues.
  • Simplified Visa Application Process
    Fillvisa aims to simplify the often complex and confusing visa application process by providing guided step-by-step assistance for filling out visa forms, reducing the likelihood of errors.
  • Time-Saving Convenience
    The platform allows users to complete visa applications online from the comfort of their home, saving time that would otherwise be spent visiting embassies, consulates, or hiring expensive immigration consultants.
  • User-Friendly Interface
    The website is designed to be accessible and easy to navigate, making it approachable for users who may not be tech-savvy or familiar with visa application procedures.
  • Support for Multiple Visa Types
    Fillvisa typically covers a range of visa categories and destinations, offering a one-stop solution for different travel needs including tourist, business, and other visa types.
  • Error Reduction
    By providing structured forms and validation checks, the platform helps reduce common mistakes in visa applications that could lead to delays or rejections.

Possible disadvantages

  • Limited Transparency on Pricing
    Some users may find it difficult to determine the full cost of services upfront, as additional fees beyond government visa charges may not always be clearly displayed before starting the process.
  • Not a Government-Affiliated Service
    Fillvisa is a third-party service and not directly affiliated with any government or embassy, which means users are paying extra for a service they could potentially do themselves for free through official channels.
  • Limited Reviews and Track Record
    As a relatively lesser-known platform, there may be limited independent user reviews and verified testimonials available, making it harder for potential users to assess the reliability and quality of the service.
  • Potential Data Privacy Concerns
    Visa applications require highly sensitive personal information such as passport details, financial data, and biometric information. Entrusting this data to a third-party platform carries inherent privacy and security risks.
  • Limited Customer Support Options
    Users may experience difficulties reaching customer support in a timely manner, especially if issues arise during critical stages of the visa application process, which could lead to frustration and delays.

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 response—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.

Questions & Answers

As answered by people managing code-prettify and Filllvisa.

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.
