6 Best Wappalyzer Alternatives in 2026 (Compared)

Teams leave Wappalyzer when the API becomes the product. Pro at $250 a month includes no API credits, so API buyers start at Business, $450 a month. Included credits expire after 60 days, and the lookup API runs at 10 requests a second (Wappalyzer pricing, September 2026; Wappalyzer lookup docs, September 2026).

Wappalyzer also publishes no price for 1M lookups. Its lead lists carry emails and phones scraped from public pages, with no accuracy promise (Wappalyzer lead list FAQ, September 2026). The hosted MCP server is read-only, has three tools and needs Business.

This page ranks six alternatives for readers who pull data in code or through an agent. Some replace the technology detection. One adds the people. For the full Wappalyzer price ladder, read Wappalyzer pricing.

TL;DR

Prices are monthly list, USD, checked September or October 2026. Sources sit in each section below.

What we evaluated

• Technology data. Does the tool tell you what a company or site runs, and can you filter by it?
• People. Can you get decision-makers and contact data at the companies you find?
• API limits. Rate limit, batch size and bulk export.
• Agent access. Is there a hosted MCP server that returns data?
• Price at 1M records a month. Monthly list price first, billed-yearly figure after it, with a source and the month checked.

1. LeadOcean: best for contacts at companies that use a technology

LeadOcean is a people and company database with a technology filter. POST /v1/people/search and POST /v1/companies/search take technologies (product names) and technologyCategories (105 of them, such as CRM or Analytics). On people search, add title, level, country and size to get the people at those companies. It covers 693M people and 63M companies through REST and a hosted MCP server with 12 tools.

Technology data comes from about 7.8M crawled sites. That is narrower than a pure technographics vendor. It tells you a company runs a CRM or an analytics tool, and POST /v1/companies/enrich returns the record with a company_detected_technologies object (LeadOcean OpenAPI, September 2026). It does not scan a site live or keep a per-domain history.

The reason to pick it is the bill and the output. Pro is $499 a month with unlimited searches, enrichments and lookups, 100 requests per second per key and 5 API keys. There are no credits, so 1M rows costs the same as 10k. On 2026-10-02 a free count for technologyCategories CRM, VP or C-Team, Sales & Business Development returned 1,963 mailable people (verified, catch-all valid or catch-all emails).

Pros

• Filters people by technology, title, level and country in one call.
• One flat price. No credits, no per-record price, no overage invoice.
• 100 requests per second per key, ten times Wappalyzer's lookup limit.
• Hosted MCP server with OAuth sign-in and 12 tools. Counting an audience is free.
• Free plan: 1,000 records, no card, same API and MCP server as Pro.

Cons

• No live site scan, no per-domain technology history and no trend reports.
• Technology data covers about 7.8M crawled sites, not the whole database.
• Past the fair-usage line, a very large month is paced down to one request a minute. One email to support raises the headroom.
• The app is an Exports page, not a report builder or a CRM.

Best for: engineers, RevOps and agents that need verified contacts at companies filtered by technology, at a fixed monthly bill.

Pricing: Free is 1,000 records one-off. Pro is $499 a month, flat. See LeadOcean pricing, checked September 2026.

2. BuiltWith: best for deep technology history and spend data

BuiltWith is the closest like-for-like swap, and the deeper one. It tracks 127,688 technologies on 491.9 million domains and keeps usage history going back 18+ years. It also estimates what a site spends on web technologies (BuiltWith plans, October 2026). Wappalyzer's pages do not describe that history or spend data.

The API has a published reference. One credit buys one lookup on the Domain, Relationships, Tags and Keywords endpoints. The Lists API, which pulls every site on a technology, needs a subscription and shows no credit price (BuiltWith API reference, October 2026).

Limits are tighter than they look. The API allows 10 requests a second and 8 at once, and a dedicated endpoint is the only way past that. The MCP endpoint takes your API key as a Bearer token. Contacts are exportable, but EU and California personal data is removed.

Pros

• Technology history and usage trends over 18+ years.
• Website spend data and 127,688 tracked technologies.
• Individual site lookups are free forever.
• MCP endpoint and AI agent access on the plans.

Cons

• Basic is $295 a month, above Wappalyzer Pro, and covers 2 technology reports.
• 10 requests a second and 8 concurrent requests.
• Lists and keyword search need a subscription, with no public credit price.
• Contacts are filtered, with no verified-email promise.

Best for: analysts and agencies that need the full technology profile of a domain, its history and its spend.

Pricing: Basic $295, Pro $495 and Team $995 a month, or $2,950, $4,950 and $9,950 billed yearly (BuiltWith plans, October 2026). Team includes 1.2 million API credits for domain lookups, and the page does not say whether they renew each month (BuiltWith Team, October 2026). BuiltWith publishes no 1M price. See BuiltWith alternatives.

3. TheirStack: best for companies by technology and hiring signals

TheirStack finds companies by the technologies they use and the jobs they post. Every API plan includes the Job Search, Company Search and Technographics endpoints, plus webhooks and an MCP server (TheirStack plans, September 2026). It is a clean swap for a Wappalyzer lead-list pull.

The meter is the catch. A job costs 1 API credit, and a company or a full tech stack costs 3 (TheirStack credits docs, September 2026). So 1M tech stacks is 3M credits, and TheirStack lists no 3M tier. We found no person or contact records.

Paid accounts run at 4 requests a second, and credits expire 12 months after purchase (TheirStack rate limit docs, September 2026). The hosted MCP server at api.theirstack.com/mcp signs in with OAuth or an API key and spends credits at the API rate (TheirStack MCP docs, September 2026).

Pros

• Technographics, Company Search and Job Search in every API plan.
• A published price ladder from $49 to $5,500 a month.
• Free plan with 200 API credits and 50 company credits a month.
• Credits last 12 months, against 60 days on Wappalyzer plan credits.
• Hosted MCP server with OAuth and API-key sign-in.

Cons

• A company or tech stack costs 3 credits, three times a job.
• 4 requests a second on paid plans, below Wappalyzer's 10.
• No people or contact records that we found.
• Credits are prepaid, and the pricing page shows monthly figures only.

Best for: teams that build lists from technology plus hiring signals and have a separate contact source.

Pricing: Free is 200 API credits and 50 company credits a month. API plans run from $49 a month for 1,500 credits to $5,500 for 5,000,000 (TheirStack pricing, September 2026). There is no billed-yearly figure. 1M tech stacks is 3M credits and no tier fits, so the next published tier is API 5M at $5,500.

4. Crustdata: best for tech stacks and people from one API

Crustdata is the single-vendor swap if you also want people. Technographics sits on the existing Company and Job APIs. Company Search filters by technology, and Company Enrich returns the detected stack (Crustdata technographics docs, September 2026).

It is a beta, gated add-on, and access needs field-level permission on your account. Enrich adds 2 credits per company on top of the base 2. A technographics filter adds 1 credit per search result on top of 0.03 (Crustdata pricing docs, September 2026).

Crustdata runs a hosted MCP server at install.crustdata.com/mcp, with OAuth for interactive clients and an API key for code (Crustdata MCP docs, September 2026). The weak point is volume. Default limits are 15 requests a minute on enrich and 30 on search (Crustdata rate limits, September 2026). See Crustdata alternatives.

Pros

• Tech stack, job postings and people in one API.
• Company Search filters by technology.
• Hosted MCP server with OAuth and API-key sign-in.
• Batch person enrich takes up to 10,000 identifiers a job.

Cons

• Technographics is a beta add-on that needs field-level permission.
• No dollar price per credit and no plan list on the pricing page.
• Default limits of 15 requests a minute on enrich and 30 on search.
• The contact endpoints need an enterprise plan.

Best for: teams that want stack and people data from one vendor and can negotiate a contract.

Pricing: the pricing page lists no plans or dollar prices. A Crustdata blog post reports a lowest tier from $95 a month (Crustdata pricing, September 2026; Crustdata blog, September 2026). 1M tech stacks is 4,000,000 credits (2 base plus 2 for technographics). With no public price per credit, there is no public 1M price (Crustdata docs, September 2026).

5. Coresignal: best for company records with dated technology fields

Coresignal is the volume pick if you want a company database with technology as a field. Its homepage claims 70M+ company records and 907M+ employee records (Coresignal, September 2026). Search by filter is free (Coresignal docs, September 2026).

The Clean Company API returns a technologies array, with the date each technology was first and last verified (Coresignal docs, September 2026). That gives you dated change signals that Wappalyzer's lookup response does not describe. A company record costs 10 credits, so tech lookups are not cheap.

Rate limits rise with the plan, from 5 requests a second on Starter to 100 on Scale (Coresignal rate limits, September 2026). The hosted MCP server has 5 tools and OAuth 2.1 sign-in (Coresignal MCP docs, September 2026). See Coresignal alternatives.

Pros

• Tech stack with first and last verified dates per technology.
• A published plan ladder from $49 to $5,000 a month.
• Bulk Collect takes up to 10,000 records per request.
• Search by filter is free.

Cons

• A company record is 10 credits, so tech-stack volume gets expensive.
• Credits reset each cycle on plans below Premium.
• Rate limits start at 5 requests a second.
• Contact enrichment is 20 credits a call, and the API starts at Pro.

Best for: data teams that pull company records at volume and want dated technology fields.

Pricing: monthly list is Mini $49, Starter $199, Pro $499, Growth $1,000, Premium $1,500, Scale $3,000 and Elite $5,000. Billed yearly, Starter is $2,149 a year and Elite is $54,000 a year (Coresignal pricing, September 2026). 1M company records is 10,000,000 credits, which is one Elite month at $5,000 list. The pricing page shows Get started on Elite but flags Premium, Scale and Elite for sales contact, so expect a sales call at that size.

6. Apollo: best for technology search plus contacts, priced per seat

Apollo is a sales platform with a technology filter in its API. Organization Search finds companies by the technologies they use, across 1,500+ supported technologies. Apollo says it calculates that data from multiple sources (Apollo organization search docs, October 2026).

Credits are the meter. Organization Search costs 1 credit per page of up to 100 results, and organization enrichment costs 1 credit per company (Apollo API pricing, October 2026). Each search returns at most 50,000 records, so a big pull needs many narrow queries.

Every plan includes API access. Paid plans get 200 search requests a minute and 50,000 a day (Apollo rate limits, September 2026). Apollo runs an official MCP server at mcp.apollo.io/mcp on any plan, including Free (Apollo MCP docs, September 2026). See Apollo alternatives.

Pros

• Technology search across 1,500+ technologies, with contacts in the same account.
• Free plan with API access and MCP.
• Organization search is 1 credit per page, not per company.
• Hosted MCP server with OAuth or an API key.

Cons

• Priced per seat, and credits expire at the end of each billing cycle.
• A search returns at most 50,000 records.
• We found no per-domain technology history in the docs.
• Phone numbers cost 8 credits each.

Best for: sales teams that want technology-based account lists and contacts in one seat-priced tool.

Pricing: per seat a month, billed monthly: Free $0 with 75 credits, Basic $65 with 2,500, Professional $99 with 4,000 and Organization $149 with 6,000 (minimum 3 seats). Billed yearly it is $49, $79 and $119 per seat a month (Apollo pricing, September 2026). There is no public 1M price for company tech data. 1M work-email lookups is 1,000,000 credits, or $24,750 a month at list on 250 Professional seats, a derived figure. Apollo prints no public price for extra credits.
