Features and specs

What each product offers, as listed by its team.

FingerprintJS 5 features
Stract API 0 features
  • Unique Visitor Identification
    FingerprintJS provides a robust method for uniquely identifying users by generating a fingerprint based on their device and browser configurations. This helps in tracking user activities and preventing fraud without relying on more intrusive methods like cookies.
  • Privacy-Friendly
    Unlike cookies, FingerprintJS offers a way to identify users without storing personally identifiable information on their devices. This helps in maintaining user privacy while still achieving the goal of user identification.
  • Cross-Browser Tracking
    It allows for tracking users across different browsers and even when cookies are cleared, providing a more consistent identification method that is less affected by user actions compared to traditional cookie-based tracking.
  • Open-Source Version
    FingerprintJS offers an open-source version that can be used for free, allowing developers to integrate basic fingerprinting functionalities without incurring costs, which can be beneficial for small projects or startups.
  • Highly Accurate
    By combining multiple data points such as screen resolution, browser plugins, and timezone, FingerprintJS achieves high accuracy in differentiating users, thereby reducing the likelihood of false positives.

Possible disadvantages

  • Potential for Device Blocking
    Some users may have browser extensions or settings that actively block fingerprinting attempts, which could lead to incomplete data or inability to track those users effectively.
  • Ethical Concerns
    Even though fingerprinting is less invasive than cookies, it still raises ethical questions regarding user tracking and consent, as many users may not be aware they are being tracked in this way.
  • Performance Overheads
    Implementing FingerprintJS can introduce some performance overhead as the system must collect and process multiple data points to generate a fingerprint, which could affect loading times.
  • Complexity in Implementation
    Integrating FingerprintJS, especially the more advanced features, may require a more significant development effort and understanding of client-side data handling, which could be a barrier for smaller teams or projects.
  • Legal and Compliance Issues
    Depending on regional privacy laws like GDPR or CCPA, using fingerprinting technology may require additional consent from users, leading to legal implications if not handled properly.

Questions & Answers

As answered by people managing FingerprintJS and Stract API.

Who are some of the biggest customers of your product?

Stract API's answer:

Legal services and title companies are growing segments for Stract API

Which are the primary technologies used for building your product?

Stract API's answer:

The primary technologies used in build Stract API are LLMs, Typescript, React, and Java.

What makes your product unique?

Stract API's answer:

Stract API is different because it lets the people closest to the questions get answers straight from their documents, with no templates, no custom tooling and no manual data entry. You upload your files, describe the data you need in plain language, and Stract API runs every document in the batch from start to finish. It returns clean, structured results you can put to work right away. You choose the model that fits the job, from fast, economical options for high-volume work to the newest, most capable LLMs for your highest-stakes analysis. Under the hood, it draws on techniques from the latest AI research to improve the quality of what gets extracted. The same analysis costs less than 10% of the equivalent staff time, so your team can skip the grind and go straight to analysis. And because sensitive work is the norm for many of your users, Stract API is fully SOC2 compliant, so your documents stay yours.

Why should a person choose your product over its competitors?

Stract API's answer:

A person should choose Stract API over its competitors because it gets them from a pile of documents to usable data with the least effort and risk. They describe what they need in plain language, so they don't build templates or learn a tool's vocabulary. They can use the point-and-click UI or the API for automated workflows, so the same product works for a one-off project and for a recurring pipeline. They also keep control over the tradeoff that matters most to them. They pick the model for each job, from fast, economical options for high-volume work to the newest, most capable LLMs for high-stakes analysis, instead of paying top-tier prices for everything. The extraction itself uses techniques from the latest AI research to improve quality. The cost is under 10% of the equivalent staff time, and results come back fast even on huge batches. Finally, Stract API is fully SOC2 compliant, which matters to teams handling case files, sources and survey data. Together, that means a team clears its "Needs Attention" pile and gets to analysis faster, without trading security or depth for speed.

How would you describe the primary audience of your product?

Stract API's answer:

The primary audience for Stract API is small-to-mid-sized teams, along with enterprises, that run recurring, document-heavy workflows and need to pull consistent information out of growing batches of files faster than manual review allows. These teams are typically staff-constrained, facing rising intake volumes of contracts, case files, forms or survey responses, and working from question lists that keep changing over time. Buyers tend to be operations leaders, legal and contract review leads, insurance claims intake leads, research leads, marketing and CRM operations managers, and engineering teams responsible for pipeline automation. Day-to-day users include the document reviewers who need the extracted information and the developers and analysts who feed that structured output into downstream systems. The audience spans insurance and claims, legal (contracts, discovery and case files), journalism (FOIA releases, court records and meeting minutes), marketing (reviews, support tickets and call transcripts), social science (surveys, interviews and field notes) and academic research. Stract API is a weaker fit for organizations that only need occasional one-off extraction from a handful of documents, or teams committed to strictly template- or regex-driven extraction rather than plain-language field specifications.

What's the story behind your product?

Stract API's answer:

Stract API grew out of founder Matt Moreno's repeated frustration with the same problem. At a construction tech startup in Google's accelerator, his team built an LLM feature that matched a crew's plain-language daily report to labor and material options. It worked, but it was fragile. Parsing the output was hard, bad output was constant, and any change to the structure broke it. When he asked a Google director whether a product existed to extract arbitrary structured data from unstructured text, the director said no, but that Google probably should build one. Later, on a venture to automate land title research, he again spent tens of hours building flexible document extraction. That work pulled him away from the core mission, and he wished a third-party service would handle it. When he had time this summer (2026), he found few existing solutions. Remembering the director's words, he built Stract API, which took five months to reach MVP. It lets users describe the information they want, from simple facts to judgment-heavy analysis, and returns a spreadsheet, CSV or JSON from their documents.

  • Precursor
    This (agent detection) is now a kind of emerging space. Obviously it'll get much more important, too. Other products in the space: - Foil (https://usefoil.com/), I'm biased, a friend is building this - Kasada https://www.kasada.io/ -... - Source: Hacker News / 4 months ago
  • EU Member States (and Google) suddenly want to keep cookie banners
    Cookies are not the meta for tracking. Fingerprinting [1] is highly effective across IPs and across incognito/browser profiles. The only browsers I've found that defeat it on desktop are Mullvad and Tor Browser as well as most antidetect... - Source: Hacker News / 5 months ago
  • Show HN: DevicePrint – device fingerprinting without cookies
    What differentiates this from http://fingerprint.com/? Visited for the first time and it said I already visited 800+ times with a 99.5% accurancy - not very promising. - Source: Hacker News / 10 months ago
