Available as a service
The provider runs the application and its infrastructure so customers can focus on using the product rather than installing and operating it.
Software as a Service
Software delivered and operated as an ongoing online service instead of installed once and left for the customer to maintain.
In plain language
SaaS is software people access over a network—often through a browser—while the provider operates the application and its shared foundations. Customers use and configure the product without having to manage the servers, deployment, and underlying infrastructure themselves.
SaaS describes how software is delivered and operated, not whether it is useful or whether it charges a subscription. A credible service still needs clear ownership, dependable operations, secure data boundaries, and a product people genuinely need.
The foundation
What matters in SaaS
Continuously operated
Monitoring, security updates, support, backups, and careful releases continue after the first launch.
Clear data boundaries
Roles, organizations, permissions, and data ownership stay explicit even when products reuse shared infrastructure.
Applied by The Forge
How we put it into practice
We treat SaaS as a long-lived product and operating relationship—not as a website with accounts added at the end.
Validate the product need
We identify the users, recurring problem, operating model, and evidence that make an ongoing service worthwhile.
Reuse dependable foundations
Authentication, permissions, billing, communication, and other shared capabilities are reused where they fit instead of rebuilt without reason.
Design for operation
Deployment, observability, support, privacy, backups, and incident recovery are considered as product requirements.
Evolve from evidence
Real usage, customer feedback, and measurable outcomes guide small, reviewable improvements after launch.
A useful boundary
What it is not
- It is not simply any website that includes a login screen.
- It is not a build-once project: operating and improving the service is part of the product.
- Shared infrastructure does not mean customer data should be shared or weakly isolated.
A concrete example
A community platform
A community organization uses an online platform for members, activities, and communication. The provider operates one evolving product, while each organization keeps its own roles, configuration, and protected data.
