Slack is a cloud-based team collaboration and messaging platform developed by Slack Technologies, which launched in August 2013 and became a subsidiary of Salesforce in 2021. It organizes workplace communication into channels, direct messages, and threads, and supports file sharing, voice and video calls, and integration with third-party applications. On websites it is commonly detected through embedded widgets, community invite links, and integrations that connect a site to a Slack workspace.

The Slack dataset

Every site we've detected as running Slack, with version, hosting, country, TLD and traffic rank.

Slack lives inside 2 datasets

Slack detection is part of Technologies (€159/mo) and All data (€599/mo). Buy either to filter the full 28,062-site list, or grab a free preview first.

Your Slack downloads

The datasets you own, sliced to Slack. Every button streams the latest daily export directly.

Format: JSONL (zstd) Dataset updated: 2026-08-18

API, columns & recipes → /account/api

Which websites are using Slack?

webatla detects every site using Slack and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.

Open the Slack technology dataset to break adoption down by country and TLD, compare it with a competing technology, and track new domains over time.

Frequently asked questions

How many websites use Slack?

webatla detects Slack on 28K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Slack?

Yes, as structured JSONL. Grab a free sample first.

What's included for each site, and how fresh is it?

Domain, DNS, RDAP/WHOIS, the full technology stack, IP & country, PageRank and Harmonic, re-detected and re-exported daily.

How do I find the websites using Slack?

Buy the technology dataset, then download the complete list of domains we detect using Slack, re-exported every day.

What else is in the Slack technology data?

Each row places Slack next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.

Can I download just the sites using Slack, or the whole database?

Both. Every site running Slack comes in the Technologies dataset, one downloadable file. Or buy All data for the entire database: technologies plus identity, ranking, DNS and RDAP/WHOIS for every domain, combined in one file. Daily fresh export.

How do I download the list of websites using Slack?

Three steps: (1) grab the free 10,000-row sample to inspect the schema, (2) buy the Technologies dataset, (3) download the full list of every domain we detect running Slack as a JSON Lines file. It is re-exported daily, so you can re-download the freshest list any time inside your access window. Each row carries the domain plus DNS, WHOIS, IP, hosting country and rank.
