Best Wappalyzer Alternatives (2025)
| Rank | Tool | Key Use Cases |
|---|---|---|
| 1 | TechPeeker | Technology detection, lead generation, competitor analysis |
| 2 | BuiltWith | Website profiling, sales intelligence, data exports |
| 3 | WhatRuns | Browser extension for on-page tech discovery |

1. TechPeeker
Find the technology behind any website
TechPeeker tops this list because it‘s more than a simple website technology detector. It‘s a full-scale technology intelligence platform built for marketers, developers, and business owners.
You can analyze any website to detect CMS platforms, frameworks, analytics tools, ecommerce systems, and more — all in one search.
Where TechPeeker really shines is lead generation. Users can build targeted lead lists filtered by the technologies websites use (like Shopify, Next.js, or WordPress). Add built-in contact data, social links, and export features, and it becomes an essential tool for any sales or growth team.
Key Features:
- Website Technology Checker
- Lead Database with advanced filters
- Shopify & WordPress theme detectors
- Competitive analysis insights
- API & data export options
Best for: Marketers, developers, and agencies who need accurate tech stack data and qualified technology-based leads.
2. BuiltWith
BuiltWith remains a solid contender in 2025. It offers deep web technology insights and is used heavily by sales teams for prospecting and technology tracking.
Users can search for domains running on specific platforms or frameworks and access market trend data across industries.
However, BuiltWith‘s interface feels more dated compared to modern platforms like TechPeeker.
Best for: Teams needing large-scale market analysis and structured data exports.
3. WhatRuns
WhatRuns is a lightweight browser extension that detects technologies on any webpage you visit.
It‘s perfect for developers or designers who want instant, on-page insights without switching tabs.
While WhatRuns lacks the database and lead generation capabilities of TechPeeker or BuiltWith, it‘s a fast and free solution for quick tech lookups.
Best for: Developers and researchers who need quick, on-the-go website tech insights.
4. SimilarTech
SimilarTech is built for B2B sales and market research. It goes beyond detection, offering tracking and analytics for entire technology ecosystems — showing how usage of tools like Shopify or React trends over time.
Its data-driven reports are ideal for large teams, though pricing can be on the higher end.
Best for: Enterprises and market analysts seeking large-scale technology trend data.
5. NerdyData
NerdyData takes a unique approach — it‘s a source code search engine that lets you find websites by the code or technologies used in their HTML.
It‘s great for developers and SEO pros looking for niche websites using specific scripts or tags, though it‘s less beginner-friendly than other options.
Best for: Advanced users who prefer hands-on source code exploration.
