Tech stack intelligence Wappalyzer Review: Is It Still Worth It in 2026?
Wappalyzer is a tech stack intelligence tool with a Chrome extension and lead lists, best for basic tech-stack lookups on mainstream technologies. The Chrome extension is free, and Starter costs $250/month. Skip it if your ICP needs niche tech detection, you need historical adoption data for timing-based outbound, or you only need occasional single-site lookups.
Wappalyzer is a lightweight tech-stack detection tool: free Chrome extension for single-site lookups, paid lead-list product for tech-defined outbound. Cheaper than BuiltWith but tracks fewer technologies (~3K vs 700K) and lacks historical data. Best for basic tech-stack curiosity ; less compelling for serious tech-stack lead-gen.
- Your ICP touches mainstream tech stacks (HubSpot, Shopify, Stripe, WordPress, Klaviyo)
- You want clean tier pricing without per-filter complexity
- Your team uses the free Chrome extension and wants the paid lead-list upgrade
- Your ICP requires niche tech detection (the 3K-technology set will miss it)
- You need a tech-adoption signal for timing-based outbound (Derrick Signal alerts on tech-stack moves)
- You only need occasional single-site lookups (the free extension is enough)

Overview
What is Wappalyzer?
Wappalyzer is a UK-built tech-stack detection tool launched in 2008. The free Chrome extension is the product most people know: open any website, see the tech stack (frameworks, analytics, CRMs, hosting) in one click. The paid product is a lead-list builder : query Wappalyzer's database of 50M+ indexed websites by detected technology, export CSV lists with contact data. It targets tech-stack lead-gen at a lower price point, with a thinner detection set.
Pricing
Wappalyzer pricing 2026
Pricing collected from wappalyzer.com/pricing (May 2026).
| Plan | Price | Typical use | Key limits |
|---|---|---|---|
| Free Chrome extension | $0 | Single-site lookups, developer curiosity | No bulk lookups · no API · no lead lists |
| Starter | $250/month | Solo lead-gen on common tech stacks | 10,000 results/month · API access · CSV export |
| Pro | $450/month | Active lead-gen | 50,000 results/month · advanced filters · webhook integrations |
| Scale | $850/month | Mid-market workflows | 250,000+ results/month · multi-user · priority support |
| Enterprise | Custom | High-volume / custom integrations | Negotiated rates · dedicated CSM · SSO |
What the pricing page doesn't show
Result caps per tier matter: exhausting 10K on Starter forces a Pro upgrade. The 3K-technology detection set is smaller than BuiltWith's 700K: niche queries simply return zero matches. Historical adoption data is not available on any tier. For timing-based outbound, Wappalyzer doesn't deliver. Contact data is bundled but quality is uneven: many teams use Wappalyzer for the company list and enrich contacts separately.
Where Wappalyzer is fair value
If your tech-stack ICP touches the top 1,000-2,000 most common technologies, Wappalyzer Starter at $250/month gives you the same surface coverage as BuiltWith Pro at $200/month. For niche detection or historical data, it falls short. For occasional single-site lookups, the free Chrome extension is enough.
Verdict in detail
Wappalyzer Pros & Cons - Summary That Actually Helps You Decide
Pulled from G2 + Capterra verified-buyer reviews (Q1 2026), filtered for substance. Recurring themes: the free Chrome extension, simple tier pricing, and enough depth for common stacks.
Free Chrome extension, no signup
Millions of developers + sales reps have Wappalyzer's Chrome extension installed. It answers "what is this site running" in one click, free with no signup required.
Clean tier pricing without per-feature complexity
Unlike BuiltWith's per-tech-filter model (which requires Pro tier for multi-tech ICPs), Wappalyzer's tiers bundle all features. Starter ($250) covers 10K results with full API access. Pro ($450) scales results + webhooks. Predictable pricing.
Detection depth sufficient for mainstream tech-stack ICPs
For ICPs touching mainstream tech (HubSpot, Shopify, Stripe, WordPress, Klaviyo, Mailchimp, Salesforce, Intercom), Wappalyzer's 3K-technology set covers the basics. Niche detection isn't the use case here.
Detection depth lags BuiltWith dramatically
3,000 technologies vs BuiltWith's 700,000+. For niche queries (specific Shopify apps, build tools, payment processors beyond Stripe, regional CRMs), Wappalyzer simply returns zero matches. Sophisticated tech-stack ICPs hit this wall fast.
No historical adoption / churn data
Wappalyzer shows current tech stack but no history. Companies that recently switched from HubSpot to Marketo, or added Klaviyo in the last 30 days: those triggers are invisible. For timing-based outbound, you need a signal on the change itself, which Wappalyzer does not give.
Contact data bundled but quality is weak
Emails and phones are included but quality is uneven. Many teams use Wappalyzer for the company list and run contacts through a dedicated email finder such as Derrick's Email Finder (5 credits per email found).

Head-to-head: Wappalyzer vs 1 competitor
The verdict
Who should skip Wappalyzer
Wappalyzer fits mainstream tech-stack ICP outbound on a budget: the $250/month Starter tier covers the most common technologies with predictable tier pricing, no per-filter math. The free Chrome extension is widely installed, and the paid product benefits from that familiarity. The platform fails for niche tech detection and for timing-based outbound, and its bundled contacts are uneven. Derrick covers those gaps from one account: Website Technologies, Email Finder and Signal on paid plans from €20/month, after a free plan of 100 credits a month to try it.
