Changelog

July 25, 2026

Since launching TechnologyChecker 2.0 in January, we've shipped the intent layer our customers asked for most: who just adopted a tool, who dropped one, and how to get notified the moment it happens.

This update covers the major product work from January through July 2026 — Live Detection, Lead Lists, the new Signals suite, Signal Alerts, company search, and a faster detection backbone under the hood.

Shipping timeline

What's New

Live Technology Detection

Look up any domain right now, not from last month's crawl.

• On-demand analysis with full browser rendering for modern SPAs
• Multiple modes for speed vs. depth (fast HTTP, light render, full browser)
• Pattern-matched against our detectable technology catalog with confidence and version when available
• Built into domain lookup in the dashboard so you can refresh a stack without leaving the profile

Live Detection is ideal when a prospect just launched a site, switched vendors, or you need a fresh read before a call.

Lead List Builder

Build targeted prospect lists from technology + company data — without exporting and stitching CSVs by hand.

• Combine technology filters (AND / OR / exclude) with firmographics: country, industry, employee range, and more
• Fast preview counts before you spend credits
• Background processing for large lists (up to plan limits)
• Export to CSV/JSON with technology names resolved
• Plan-based concurrent list limits so Free, Pro, Scale, and Enterprise stay fair

Use Lead Lists when the question is "give me 5,000 companies using X that look like my ICP."

Signals: Adoption, Churn, Switch & Whitespace

Signals answer a different question: who changed their stack recently?

Each query supports:

• Technology or category scope (e.g. "Klaviyo" or all Email Marketing tools)
• Time windows (7 / 30 / 90 days and beyond)
• Firmographic filters (country, industry, employees, company type)
• Confidence controls so you can favor high-trust events
• Company enrichment on result rows (name, industry, location, size)

Signals cost 1 credit per query. Free plans can explore them; plan limits apply where they matter (credits and alert caps).

Signal Alerts (Webhook + Email)

Any signal query can become a subscription.

• Adoption / Churn / Switch / Whitespace presets — same scopes as the explorer
• Account Watchlist — watch named domains for stack changes (optional daily/weekly elevated crawls)
• Delivery by email or webhook (Stripe-style HMAC signing for webhooks)
• Hourly or daily digest cadence so you control noise
• Minimum confidence filters to suppress sparse/flaky detections
• Delivery history, test fire, and CSV export of delivered events

Alerts themselves don't consume flat credits; elevated watchlist crawls are metered when you opt into faster re-scans.

Confidence Scoring You Can Trust

Intent data is only useful if it's accurate. We layered quality controls on top of raw crawl transitions:

• Per-event confidence (high / medium / low + score) based on detection method, scan count, and consistency
• First-seen gate — adoption no longer treats "first time we crawled this domain" as a real install
• Churn reliability labels by detection method (headers/DNS vs. flaky script patterns)
• Guards against one-scan flap so whole-stack noise doesn't flood your inbox
• Optional churn validation to re-check borderline drop-offs live

In the dashboard, confidence shows up on explorer rows and alert deliveries with plain-language tooltips.

Signals CSV Export

Need the full set of matches for outreach or a CRM load?

• Export adoption/churn results as CSV from the explorer
• Billed at 1 credit per exported row (capped sensibly; larger extracts point you at Lead Lists)
• Includes confidence columns and company fields when enrichment is on

Company Search & Enrichment

Technology data is more useful with a company attached.

• LinkedIn company profiles at scale (industry, size, location, founded year, and more)
• Company search that unifies crawl coverage + LinkedIn (source-tagged, domain-keyed)
• Firmographics on Signals results and domain workflows
• Batch company lookup for enrichment pipelines

Faster, Fresher Detection Infrastructure

Behind the product surface we moved current-state detection onto our v2 detection engine and ClickHouse cluster — continuous crawling with cleaner active/historical separation.

What that means for you:

• Domain lookups return active technologies from the live corpus
• Signals and alerts run on real status transitions, not static snapshots
• Historical timelines remain available where you need long-range trend views
• Detectable catalog stays aligned with real patterns (Wappalyzer-class signatures plus growing coverage)

Dashboard: Technology & Category Intelligence

Technology and category pages in the app are no longer a pile of live API calls.

• Technology profiles with adoption/churn windows, competitors, firmographic breakdowns, and top companies
• Category pages with momentum (net 30-day movers), switch destinations, and rankings
• Pre-materialized profile data for speed and reliability under load

Free Tools & API Hardening

• Public free-tools endpoints for common lookups (with dedicated rate limiting)
• Plan-based API rate limits (Free / Pro / Enterprise)
• Full technologies export for catalog consumers
• API Playground coverage for Signals and Alerts (read paths)
• Billing and credits sync improvements for organizations

How Teams Use What's New

Competitive displacement

Save a Switch alert: "who left Competitor X for us / for anyone." Reach out while the evaluation is still warm.

Churn prevention

Watch adoption of competing tools among your customer domains via Account Watchlist + daily crawl cadence on critical accounts.

Outbound ICP lists

Run a Whitespace query (Shopify sites with no ESP), filter to your country and size band, then export or save as an alert for continuous flow.

Account-based selling

Paste your target account list into a Watchlist, get notified on any stack change, and open the domain profile with Live Detection before the call.

Availability

Everything above is live in production for dashboard and API customers, subject to plan credits and alert entitlements.

• Dashboard: app.technologychecker.io
• API docs & playground: available inside the product
• Signals reference: adoption, churn, switch, whitespace + export
• Alerts reference: CRUD, deliveries, email/webhook, watchlist

What's Next

We're continuing to tighten signal accuracy, grow the detectable catalog from real crawl exhaust, and close the loop from alert → list → outreach so intent events become pipeline without spreadsheet glue.

Team TechnologyChecker

January 22, 2026

We've rebuilt TechnologyChecker from the ground up with one mission: turn technology intelligence into revenue for sales teams.

For too long, technology detection tools have been browser extensions that show frontend JavaScript libraries. That's not enough. Sales teams need to know the entire tech stack, get alerted when prospects switch tools, and have verified contacts to reach decision-makers immediately.

Today, we're launching TechnologyChecker 2.0 — the only platform that combines full-stack technology detection, 20-year historical data, real-time alerts, and verified contact intelligence.

What's New

40,000+ Technologies Across 50M+ Domains

We've expanded our detection coverage to 40,000+ technologies — 10x more than any competitor. This isn't just frontend frameworks anymore.

Now detecting:

• Backend infrastructure: n8n, custom APIs, databases, server frameworks
• Standalone platforms: Airtable, Notion, Zapier, Make, Monday.com
• Frontend frameworks: React, Vue, Next.js, WordPress, Webflow
• Marketing & sales tools: HubSpot, Salesforce, Intercom, Drift
• Infrastructure: AWS, Google Cloud, Cloudflare, CDN configurations

Our dataset now covers 50M+ domains with continuous scanning and validation.

Real-Time Alerts for Technology Changes

Stop checking prospects manually. Get instant notifications when:

• Target accounts adopt competitor tools
• Prospects switch from legacy systems (buying window detected)
• Customers show churn signals by adopting competing platforms
• Companies add backend tools like n8n or Airtable (ops expansion signal)

Set custom alert rules:

• Technology adoption (e.g., "Alert me when prospects add Stripe")
• Technology removal (e.g., "Alert me when companies drop Intercom")
• Stack changes (e.g., "Alert me when prospects migrate from WordPress")
• Competitor displacement opportunities

Alerts include verified contact data so you can reach decision-makers within minutes, not days.

20-Year Historical + Live Data Combined

We've merged two decades of technology adoption history with real-time monitoring.

What this means for sales teams:

• Predict churn: See historical patterns of companies switching from your product to competitors
• Identify buying windows: Analyze when companies typically evaluate new tools after stack changes
• Competitive intelligence: Track how competitors gained or lost market share over 20 years
• Trend analysis: Understand technology adoption curves and migration patterns

Example use case: A SaaS company discovered that 73% of customers who adopted Workday within 90 days of renewal ended up churning. They now get real-time alerts and proactively address migration concerns before renewal conversations.

Verified Decision-Maker Contacts Included

Technology signals are worthless if you can't reach the right person.

Every technology profile now includes:

• Verified email addresses (deliverability confirmed)
• Decision-maker matching by role and department
• LinkedIn profile integration
• Firmographic data (company size, industry, location)
• Engagement signals (website traffic, funding events)

No more:

• Buying separate contact databases
• Cold calling receptionists
• Guessing who owns the tech stack
• Wasting time on undeliverable emails

Full-Stack Detection, Not Just Frontend

Competitors like Wappalyzer only see what's visible in the browser. We see the entire infrastructure.

Backend detection examples:

• Automation platforms: n8n, Zapier, Make, Integromat
• Databases: PostgreSQL, MongoDB, Redis (when signatures are public)
• APIs: Custom REST/GraphQL endpoints, third-party integrations
• Server frameworks: Node.js, Django, Rails, Laravel

Standalone platform detection:

• Airtable, Notion, Coda (via DNS/API fingerprints)
• Monday.com, Asana, ClickUp (project management signals)
• Internal tools with external-facing components

Why this matters: A prospect using Airtable + n8n signals they're building custom operations workflows — the perfect time to pitch your automation platform. Frontend-only tools would never catch this.

Built for B2B Sales Workflows

TechnologyChecker 2.0 isn't a browser extension add-on. It's an enterprise platform.

New capabilities:

• Bulk enrichment: Upload up to 100,000 domains, get full tech profiles + contacts
• API access: Integrate technology intelligence directly into your CRM and workflows
• CRM automation: Push alerts and contact data to Salesforce, HubSpot, Pipedrive
• Webhook triggers: Build custom workflows when technology changes occur
• CSV/XLSX export: Download historical data and contact lists for analysis
• Custom scoring models: Weight technologies based on your ICP fit

Why We Built This

We talked to hundreds of sales teams who were frustrated with existing technology detection tools. The feedback was clear:

"I don't need to know they use React. I need to know they just adopted my competitor's platform so I can reach out before they commit."

"Frontend detection alone doesn't give the full picture. I need to see backend tools like n8n and Airtable to understand their operations stack."

"Technology data without contacts is worthless. I spend hours finding the right person to email."

TechnologyChecker 2.0 solves all of this. Full-stack intelligence, real-time alerts, and verified contacts — built for revenue teams.
