# See which companies use your open source and what they do next Scarf is an open source usage intelligence platform that helps open source teams identify which companies use their software and how adoption changes over time. It connects package downloads, documentation visits, and product telemetry to the companies behind them so teams can measure adoption, prioritize accounts, and find companies that may be ready for a commercial product.

[See foundation benefits](/foundation-backed-projects) ## How does Scarf work? Bring together the signals that show how organizations discover, evaluate, and continue using your software. 1 ### Collect adoption signals Connect package and container registries, files, APIs, documentation, or product telemetry you control. 2 ### Understand company adoption See which organizations are active, what they use, which versions they run, and how engagement changes over time. 3 ### Put the data to work Prioritize accounts, follow adoption changes, export data, or send selected signals to the systems your team already uses. ![Scarf adoption funnel showing company activity from interest through ongoing usage](/imported/home/adoption-funnel.png) ### See more than a download count - Which projects and versions a company uses - When engagement started and how it is changing - Where each company sits in the adoption journey [Explore the platform](/platform) ![Liquibase](/imported/home/liquibase-logo.svg) ## Liquibase built its go-to-market model around real community adoption At Liquibase, community usage identified by Scarf is a core requirement for the company's top ICP tiers and now guides territory planning, ABM, and nurture. [Read the case study](/post/building-a-predictable-icp/) **90–95%** of new logo wins originate from Liquibase Community users **90%+** of deals are marketing-driven, powered by an ICP model that starts with Scarf signals ## Which package downloads and usage signals can Scarf track? Scarf can identify organizations downloading Docker, Helm, npm, PyPI, Homebrew, GitHub Releases, S3, Maven Central, files, and APIs, then connect those signals with documentation visits and product telemetry. Connect only the sources that fit your project, without moving your software or collecting personal data. ### Maven Central Connect a publisher namespace directly. No changes to your packages or install instructions are required. [Connect Maven Central](https://app.scarf.sh/register) ### Software distribution Track Docker, Helm, npm, PyPI, Homebrew, GitHub Releases, S3, and nearly any other place your project distributes software. ### Files and APIs Put Scarf Gateway in front of a file or API while keeping your existing host and public URLs under your control. ### Docs and websites Add a lightweight pixel to understand which organizations read your docs and open source product pages. ### Product telemetry Send selected CLI, SDK, or application events from telemetry that your project chooses to collect. ## How can teams use open source adoption data? Open source adoption signals can help revenue teams prioritize accounts, product teams understand deployment, and founders prove that adoption is real. Unstructured ### 2x higher outreach response Unstructured reported twice the response rate when outreach used Open Source Qualified Leads from Scarf. Dave Donahue, Head of Strategy Budibase ### Evidence of enterprise adoption for investors Budibase used repeat downloads from large companies to show investors that adoption was real and growing. Michael Shanks, Co-Founder and CEO Redpanda ### Kubernetes usage shaped product priorities Redpanda used adoption data to understand where Kubernetes usage was strongest and prioritize engineering work. Alexander Gallego, Founder and CEO ## Where can teams use Scarf data? Teams can save and filter accounts in Scarf, then send selected data to Slack, Salesforce, HubSpot, Common Room, or your own systems through exports, APIs, and webhooks.

Scarf is designed to identify organizational adoption without building person-level profiles. ![](/imported/home/check-icon-blue.svg) ### Zero PII stored by default Scarf identifies organizational adoption without building person-level profiles. ![](/imported/home/check-icon-blue.svg) ### Raw IP addresses are discarded Raw IP addresses are not retained or exposed in the Scarf product. ![](/imported/home/check-icon-blue.svg) ### Self-hostable Gateway Run Scarf Gateway in your own infrastructure when your project requires it. ![](/imported/home/check-icon-blue.svg) ### Accepted by open source foundations Scarf is included in benefits for projects at the Apache Software Foundation, Linux Foundation, CNCF, OWASP, and Commonhaus.
