BuiltWith Alternatives 2026: 6 Tools Compared on Price and Bulk

BuiltWith is the category reference for tech-stack detection, priced from $50 per month. Teams shop for alternatives when the billing scales by technology filter rather than by row, when the output does not land in their working file, or when the tech signal alone does not tell them who to contact. The 6 options below are compared on detection method, refresh cadence and real cost per row. Derrick App leads on per-row credit economics and on what happens to the list after detection.

Context03 / 09

A BuiltWith alternative is any tool that tells you which technologies a website runs, so you can build a target list from a tech stack instead of a job title. BuiltWith is the reference product in that category, priced from $50 per month with free single-site lookups, and most teams start their search there. They end it somewhere else for one of three reasons: the pricing scales by technology filter rather than by row, the output lives in a platform instead of in their working file, and the tech signal alone does not tell them who to contact.

That third point is the one that decides most of these evaluations. Knowing that 800 companies run a given e-commerce platform is a list, not a pipeline. What turns it into a pipeline is the layer underneath: the company record, the people in the right seats, and a verified way to reach them. So the honest way to read this comparison is in two parts: which tool detects the stack, and what happens to the rows after detection.

Derrick App leads this list because it answers the second half inside the file you already work in. You paste a list of domains in Google Sheets, and the sidebar fills in company data, similar companies, the people who work there and their verified contact details, row by row, from 20 EUR per month with a free plan at 100 credits per month. The six options below are compared on budget, workflow, use case and team size, with a frank view of where each one stops.

How to choose06 / 09

Choosing a Tech stack intelligence tool after BuiltWith

Two filters : a per-profile pick (cards below) and a granular criteria matrix (budget / workflow / use case / team size).

If the blocker is paying per technology filter

Derrick App

Derrick charges per row looked up, not per technology you want to track : €20 a month for 10,000 credits, €0.0016 per credit at the Scale tier. The same credits also pay for emails, direct phone numbers and company records on the same sheet.

See full profile ↓
If the detection has to run inside a workflow

Derrick App (REST API and MCP)

From the €47.50 PLUS plan, one authenticated call per domain returns structured JSON, so a signup, a CRM sync or a nightly job can score the stack automatically. The same account answers from Claude or any MCP client, and the web app runs the same enrichments with nothing to install.

The verdict07 / 09

Verdict : which BuiltWith alternative to pick

BuiltWith alternatives split cleanly by job, not by brand. The four profiles below cover most of the searches that land on this page.

  • You need one answer, right now : use a free single-domain check and move on. Our free website lookup tool covers that case with no account.
  • You need a column filled on a list you maintain : Derrick App is the lowest-friction fit from 20 EUR per month, with a free plan at 100 credits per month, per-row pricing and credits that roll over.
  • You need the stack to trigger something automatically : an API-first workflow is the shape to look for, and the question to ask each vendor is the cost per row at your monthly volume, not the headline plan price.
  • You need procurement-grade coverage at enterprise scale : expect annual contracts across the category, and compare on refresh cadence, coverage of your target geography and support terms rather than on monthly price.

Whatever you shortlist, run the same ten domains through two or three candidates before committing, and check the answers against companies you already know from the inside. A tech-stack tool earns its place on how it behaves on your list, not on how it behaves on a demo domain.

Which BuiltWith alternative should you pick in 2026?

+
It depends on which job you are doing. For a one-off check on a single domain, a free browser-based lookup is enough. For filling a column on a list you maintain, Derrick App runs in its web app or inside Google Sheets from 20 EUR per month, with a free plan at 100 credits per month and per-row pricing rather than per-technology-filter pricing. For enrichment that has to fire automatically inside a CRM or an app, look for an API-first option and compare the cost per row at your real monthly volume.

Is there a free BuiltWith alternative?

+
Yes for single-domain checks. We publish a free website lookup tool and a website technology lookup on derrick-app.com that need no account. For repeated bulk runs, free tiers across the category are usually capped in credits or in lookups per month: Derrick's free plan carries 100 credits per month, and a company enrichment costs 1 credit per company, so a free test list of a few dozen domains is realistic while a monthly run of thousands is not.

Can I run a BuiltWith alternative in bulk on a list of domains?

+
That is the question that separates the tools on this page. A browser extension answers one domain at a time by design. A bulk workflow needs either a spreadsheet integration that fills a column row by row, or an API you can call from your own job. Before you commit, price the same 2,000-domain month under each vendor's model: per technology filter, per seat, per lookup and per row give very different totals for the same list.

Why do two tech-stack tools report different technologies for the same site?

+
Because each one maintains its own fingerprint library and its own refresh cadence. A script loaded asynchronously can be invisible to a detector that does not execute JavaScript, a technology removed last month can persist in a crawl-based dataset until the next pass, and a CDN can mask server-level signals. Treat a detected technology as strong evidence and a missing one as weak evidence, and test any candidate on ten domains whose stack you already know.

Does a tech-stack tool give me contacts as well?

+
Usually not, and that gap is where most technographic projects stall. Detection gives you qualified domains; outreach needs the company record, the right people and a verified way to reach them. In Derrick those are separate, per-row steps: Enrich Companies at 1 credit per company, then a people lookup on the accounts that survived the filter, then Email Finder at 5 credits per email found or Phone Finder at 200 credits per number found. Email Finder and Phone Finder are paid features and bill only when they return a result.

How current is technographic data?

+
It varies by detection method, and vendors rarely publish the number, so ask. A real-time fetch reflects the site as it is when you run it. A crawl-based dataset reflects the site as it was at the last pass, which can be weeks old. On a migration-driven play, that lag is the whole game: reaching a team while they are choosing is a different conversation from reaching them a quarter after they chose.

What should I check before switching away from BuiltWith?

+
Three things, in this order. Run your ten best-known domains through the candidate and compare against what you already know. Price your real monthly volume under the candidate's billing model rather than under its headline plan. Confirm where the output lands: a column in the file you maintain, a JSON response your pipeline can consume, or a platform that will need an export every time.
