🔬 Company Tech Stacks
What is a tech stack?
A tech stack is a set of technologies that are used to build and run a software application. It includes the programming languages, frameworks, databases, servers, and other tools that are used to develop and deploy the application.
The exact components of a tech stack will vary depending on the specific application, but there are some common components that are found in most tech stacks. These include:
- Frontend technologies: These are the technologies that are used to create the user interface of the application. They include HTML, CSS, and JavaScript.
- Backend technologies: These are the technologies that are used to process the data and logic of the application. They include programming languages like Python, Java, and C++.
- Databases: These are used to store the data of the application. They can be relational databases like MySQL or PostgreSQL, or non-relational databases like MongoDB or Cassandra.
- Servers: These are the computers that run the application. They can be physical servers, virtual servers, or cloud servers.
- Other tools: There are many other tools that can be used in a tech stack, such as version control systems, continuous integration and continuous delivery (CI/CD) tools, and monitoring tools.

Tech stack FAQs
- How does Employbl know what tech stack a company uses?
- Stacks are extracted from the technologies each company mentions in its own live job descriptions — pulled directly from their applicant tracking systems — not from self-reported marketing pages. If a company is hiring for Kubernetes, that signal comes from their actual openings.
- Can I find companies and jobs by a specific technology?
- Yes. Each technology page lists the companies hiring for it right now, what it commonly pairs with, and the live roles that ask for it — across 30,000+ companies and 75,000+ listings.
- How current is the tech-stack data?
- Job listings sync from company ATSs on a daily cadence and stacks are re-derived from those listings, so a technology showing on a company reflects recent hiring — not a stale claim from years ago.
