Yes, F5 Networks owns the Nginx software project and company. If you ask is nginx owned by f5, the buyout closed in May 2019. F5 paid hundreds of millions of dollars to buy the popular web server maker. This deal brought open source web tools into a large hardware network company. Today, F5 runs both the free open source project and the paid enterprise products.
Why is nginx owned by f5 and how does it work in practice?
Igor Sysoev wrote the first version of the web server in 2002. He built it to handle ten thousand web requests at the same time. The software uses an event loop instead of making a new thread per request. This design uses very little memory under heavy web traffic. In 2011, the founders started a business to sell support and extra features.
F5 made hardware boxes that sat in data centers and routed network traffic. As teams moved apps to the cloud, they wanted small software load balancers. F5 bought the company to fill this gap in its product line. Today, engineers and AI agents deploy these web servers inside cloud containers every day.
The product line splits into two main versions for tech teams. The open source version remains free under a standard two-clause BSD license. Anyone can download the source code, run it, and change it for their apps. The paid version adds health checks, live metrics, and enterprise support from F5. Teams pick a version based on their budget and need for vendor support.
How teams manage server roles and session risks
Running web servers requires engineers and automated scripts to log in and change settings. Teams often use SSH keys or static cloud roles to reach these Linux hosts. Static keys grant broad power once a user or bot logs into the machine. A role checks who you are at login, but not what you do next.
During an active session, an engineer has full control over web routing text files. One bad edit can break TLS settings or expose internal backend apps to outsiders. Static credentials also stay on laptops where attackers can steal them later. If an AI agent holds a static key, it can run bad commands fast.

Web servers also sit close to databases that hold private user data. When teams debug traffic or query backends, raw data flows back to their screens. Static roles do not stop sensitive fields from showing up in query results. Data masking rewrites matched fields like emails, phone numbers, card numbers, and national IDs. Without command controls and masking, active sessions leave critical apps and data at risk.
Open source changes and community forks after the buyout
When a big vendor buys an open source tool, users worry about license changes. F5 kept the core web server free and open under the original license. Still, some original developers left the company a few years after the deal closed. In 2024, a key core developer started a free fork called Freenginx. He wanted a project run by developers without corporate goals driving the code.
For most teams, the main F5 branch still gets regular security fixes and updates. Major Linux distributions still ship the standard version in their default package managers. Teams must weigh vendor backing against community control when choosing their web server software. Regardless of the branch, securing how staff and bots touch those servers comes first.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
When did F5 buy the Nginx company?
F5 announced the deal in March 2019 and closed it in May 2019. Since that date, the web server team has worked as a unit inside F5.
Is the open source web server still free to use?
Yes, the open source edition remains free to download, run, and modify. It still uses the permissive two-clause BSD license for both personal and business use.
What is the difference between the free version and F5 Nginx Plus?
The free version gives you core web serving, reverse routing, and basic load balancing. The paid version adds active health checks, session persistence, live status APIs, and support.
