7 Best Bloomberry Alternatives in 2026

7 Best Bloomberry Alternatives (And What They Actually Do Better)

You pulled 500 companies that just adopted Salesforce from Bloomberry. Your SDR asks: "Cool, who do I email?" And you realize you need a different tool entirely.

That's the core tension with every technographic platform - they tell you what companies use, not who to talk to. The technographic market is weirdly fragmented, and you almost always need two tools: one for detection, one for contacts. Here are seven Bloomberry alternatives that fill different gaps depending on where your workflow breaks down.

Bloomberry covers web technologies plus 1,200+ B2B products across 180 categories, with real-time churn and renewal signals powered by DNS records and sources beyond web scraping. It's genuinely strong for backend and SaaS detection - CRMs, security tools, AI products - where frontend scrapers can't reach. A good example: Bloomberry flagged fieldlogix.io as churned from Intercom even though the Intercom script was still on the site (the widget had stopped working). That's impressive. But Bloomberry doesn't give you contact data. Neither do most of its competitors.

Our Picks (TL;DR)

Best Bloomberry Alternatives in 2026

Prospeo - Find the People Behind the Tech Signal

Bloomberry finds companies. Prospeo finds the decision-makers at those companies. That's the workflow most sales teams actually need: identify 500 companies running Okta, then pull verified emails and direct dials for the security leads at each one.

Prospeo's database covers 300M+ professional profiles with 143M+ verified emails and 125M+ verified mobile numbers. Email accuracy sits at 98%, backed by a proprietary 5-step verification process that includes catch-all handling, spam-trap removal, and honeypot filtering. Data refreshes every 7 days - most competitors update every 4-6 weeks, which means you're emailing people who changed jobs a month ago. Search with 30+ filters including technographics and buyer intent across 15,000 topics, then export directly to Salesforce, HubSpot, or your sequencer.

We've seen teams pair Bloomberry's tech detection with Prospeo's contact data and cut their prospecting time in half. The free tier gives you 75 emails and 100 Chrome extension credits per month - enough to test the workflow before committing. Paid plans run about $0.01/email with no contracts.

Skip it if you're purely doing market sizing or competitive intelligence and don't need to contact anyone.

BuiltWith - The Biggest Tech Database

BuiltWith is the incumbent everyone benchmarks against: 414 million domains, 113,027 tracked technologies, and history going back over four decades. Nobody else comes close on raw coverage.

The catch is pricing. The Basic plan at $295/mo only covers 2 technologies - if you're tracking 10+, that's a painful limitation. Pro jumps to $495/mo, Team to $995/mo with a 100k/mo API credit cap. And there's no contact data whatsoever.

Compared to Bloomberry, BuiltWith excels at frontend detection and historical trends but can't match Bloomberry's backend/SaaS detection. If you need both, you're running two subscriptions. For teams doing competitive displacement campaigns where historical adoption data matters, BuiltWith is still the gold standard. For everyone else, the price-to-value ratio gets hard to justify.

Wappalyzer - Browser-First Tech Lookups

Wappalyzer is the tool most people try first because the browser extension is free and instant. Point it at any website, get a clean breakdown of frontend technologies. It scores 4.7/5 on G2, and users consistently praise the accuracy for client-side tech detection.

The free tier gives you 50 lookups per month. Pro starts at $250/mo with 5,000 lookups, Business runs $450/mo, and Enterprise starts at $850+/mo. One quirk worth knowing: API credits expire after 60 days, so don't stockpile them.

The biggest gap? Wappalyzer misses niche and backend technologies that Bloomberry catches - a limitation that comes up repeatedly in Hacker News threads about technographic tools. If you only care about frontend stacks (analytics, chat widgets, CDNs), Wappalyzer's free tier is hard to beat.

TheirStack - Job-Posting Tech Signals

Here's a clever angle. TheirStack analyzes 180M+ job postings from 195 countries to infer what companies use based on what they're hiring for. If a company posts 12 Snowflake engineer roles, they're a Snowflake customer - no web scraping needed.

This catches technologies that leave zero frontend footprint: internal DevOps tools, data infrastructure, security platforms. The free tier includes 50 credits/mo, with paid plans at $59/mo (Starter), $169/mo (Pro), and $400/mo (Scale).

Skip it if you need historical trend data or real-time churn signals. Job postings are a lagging indicator compared to Bloomberry's DNS monitoring. By the time a company posts a job for a new tool, they've already been using it for weeks or months.

HG Insights - Enterprise Install Base

HG Insights is the enterprise play - think Fortune 500 TAM analysis and competitive displacement campaigns. It isn't self-serve. Expect $20k-$60k/year depending on modules and seats. Strong tool, wrong fit for most SMB sales teams. If you're spending six figures on enterprise deals and need board-ready market sizing data, HG Insights earns its price tag. Everyone else should look elsewhere.

SimilarTech - Affordable Competitor Intel

SimilarTech offers frontend detection starting at $200/mo, with an Ultimate tier at $490/mo. The small review sample on G2 (12 reviews, 4.2/5) and accuracy issues flagged by users make it a secondary option. Try BuiltWith or Wappalyzer first.

Datanyze - Budget SMB Option

Datanyze starts around $30/mo, making it one of the cheapest entry points for basic technographic data. Limited depth compared to BuiltWith or Bloomberry, but for small teams who need directional tech detection without enterprise pricing, the price is hard to argue with. Don't expect backend detection or churn signals - this is a "good enough" tool for teams where technographics are a nice-to-have, not the core of the outbound strategy.

Other niche options worth a look: Hunter TechLookup for quick single-domain lookups, WhatRuns as a free browser alternative to Wappalyzer, and Tagstack for GTM container auditing.

When You Don't Need an Alternative

Don't switch if any of these apply:

• You need backend/SaaS detection (CRMs, security tools, DevOps, AI products) that frontend scrapers miss entirely
• Churn and renewal signals are central to your outbound strategy - no other tool in this list matches Bloomberry's real-time alerting
• You're using technographic data for investment research through Revealera's 6+ years of historical data

Let's be honest: if your average deal size sits below five figures, you probably don't need Bloomberry-level backend detection at all. Wappalyzer's free tier plus a contact data tool will get you 80% of the way there. Bloomberry's real value kicks in when you're running six-figure enterprise deals and need to know exactly which security stack a prospect is running before the first call.

FAQ

Is Bloomberry free?

Yes, Bloomberry offers free access to get started - you can sign up, access the API, and download datasets without a credit card. For larger usage, pricing isn't listed publicly and you'll need to contact their team.

Does Bloomberry provide contact data?

No. Bloomberry identifies which companies use specific technologies but doesn't provide emails or phone numbers. Most teams pair it with a contact data platform to close that gap.

What's the best free alternative to Bloomberry?

TheirStack and Wappalyzer both offer free tiers - 50 credits/mo and 50 lookups/mo respectively. For contact data specifically, Prospeo's free plan includes 75 verified emails per month with no credit card required. Combining Wappalyzer for detection with Prospeo for contacts covers most outbound use cases at zero cost.
