Adding a contact form to a website is one of the best ways for potential clients to get in touch quickly. Unfortunately, as soon as such forms appeared, various hackers discovered ways to misuse them for malicious purposes. As a result, many site owners have to deal with inboxes flooded with unwanted messages, causing disruptions to everyday operations and compromising the overall user experience.
CAPTCHAs were created as a response to these malicious submissions. However, a kind of arms race quickly developed: while hackers strive to program bots capable of solving CAPTCHAs, developers aim to make these CAPTCHAs ever more resistant to automated attacks. In this article, we’ll explore the history of CAPTCHAs, look at popular current solutions, and explain why Mosparo stands out as the ideal alternative to protect your forms without infringing on user privacy.
A Brief History of CAPTCHAs
The term CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It’s a technology specifically designed to distinguish human users from automated programs (bots). Its primary purpose is to block bots while providing a smooth experience for real human users.
- Early CAPTCHAs: The first CAPTCHAs, emerging in the early 2000s, took the form of distorted text embedded in images. Users had to type in the characters displayed to prove they weren’t bots.
- Continuous Evolution: As automated programs grew more sophisticated, CAPTCHAs evolved to include puzzles involving selecting pictures or interacting with specific areas on a screen.
- New Challenges: Modern CAPTCHAs, although effective, can sometimes hinder user experience, especially for individuals with disabilities. They’ve also raised concerns regarding data collection and privacy.
In response to these evolving needs, numerous providers launched proprietary CAPTCHA solutions. The most prominent include reCaptcha (Google), hCaptcha (Intuition Machines), and Turnstile (Cloudflare). Yet, each of these comes with certain drawbacks, paving the way for more privacy-friendly alternatives like Mosparo.
Popular Solutions: reCaptcha, hCaptcha, and Turnstile
Several leading CAPTCHA solutions dominate the market today. Each has its advantages and disadvantages, often tied to cost, ease of use, or data management.
- reCaptcha (Google)
- Pros: Likely the most well-known CAPTCHA solution. Its initial versions required users to type distorted text or select specific images. More recent versions aim to be more “invisible,” automating much of the process for users.
- Cons: While “free,” it entails significant data collection and analysis by Google for advertising and tracking purposes. This data exchange can become a major issue for websites prioritizing user privacy.
- hCaptcha (Intuition Machines)
- Pros: hCaptcha markets itself as a more privacy-conscious alternative to reCaptcha. The data collected is comparatively limited and not used for targeted advertising.
- Cons: The service is paid for businesses, starting at $99 per month. This price may deter small website owners or those operating on a tight budget.
- Turnstile (Cloudflare)
- Pros: A relatively new offering, Turnstile aims for a seamless user experience, employing an “invisible” approach similar to reCaptcha.
- Cons: Like reCaptcha, Turnstile is “free” but comes with data collection and analysis by Cloudflare. According to its privacy policy, these data may be used for various purposes—something not all projects can accept.
Although these three are quite effective at filtering spam, they pose challenges for site owners who prioritize privacy or want to retain total control over their data. Mosparo, on the other hand, is an open-source, self-hosted alternative that emphasizes both privacy and user-friendly design.
Why Choose Mosparo?
Mosparo is a new-generation CAPTCHA solution whose popularity is steadily growing. In contrast to proprietary products, Mosparo offers several noteworthy advantages:
Enhanced Accessibility
Puzzle- or image-based CAPTCHAs can be challenging for people with disabilities, as they often rely on visual cues or intricate interactions. By contrast, Mosparo relies solely on standard HTML elements.
- Screen-Reader Compatibility: Simple HTML elements are easily detected and interpreted by screen readers.
- Inclusive Experience: Typically, users only need a click, tap, or keystroke to activate the anti-spam protection, then repeat that action to submit the form.
- WCAG Compliance: Mosparo has been tested for full compliance with the WCAG 2.1 guidelines, at both A and AA levels, ensuring it meets accessibility requirements.
Privacy by Design
Mosparo was developed with the protection of personal data as a top priority. Unlike other solutions that collect extensive user data, Mosparo only gathers what is strictly necessary.
- Data Processed: Only data entered in the form fields, the IP address, and the browser’s user agent are recorded.
- No Cookies: No cookies are placed on users’ devices, reducing tracking across websites.
- Compliant with Best Practices: Because it does not rely on hidden data collection, Mosparo can more easily help websites adhere to privacy regulations such as the GDPR.
Efficiency Based on Custom Rules
Mosparo filters spam using admin-defined rules, much like email spam filters.
- Tailor-Made Filters: Site administrators can add keywords that rarely appear in legitimate messages. If a bot tries to submit a message containing these words, Mosparo immediately blocks the submission.
- Adaptability: You can refine these rules depending on the types of spam your site faces, boosting the solution’s effectiveness.
Customization and Flexibility
Another major advantage is Mosparo’s adaptable design, both visually and functionally.
- Honeypot Option: Adds an invisible field that humans won’t see, but bots often fill out, triggering an automatic block.
- Minimum Fill Time: Require a minimum time for completing the form, making it more difficult for fast bots.
- Delaying and Auto-Blocking: When multiple submissions are received in a short span, Mosparo can delay or completely block access.
- Custom Look: You can adjust colors, sizing, and other visual parameters to match your site’s design seamlessly.
Open-Source, Self-Hosted Solution
Unlike many proprietary CAPTCHA solutions, Mosparo is open source and free. You can install it on almost any standard web hosting, giving you full control over your form’s anti-spam features.
- Independence: You’re not tied to any external service provider.
- Enhanced Security: Data doesn’t get sent to a third-party platform.
- Active Community: The open-source community continuously works on improvements, bug fixes, and new features.
