Consulting services

API development

As a SaaS application development company, we build APIs to enable fast and secure connections between services, as well as improving integrability with third-party software.

The benefits of software-as-a-service development


Being a development company with SaaS expertise, we build applications that are accessible from any device, anywhere in the world. All that users need is a stable Internet connection.


In addition to SaaS application development services, Altoros assists you in implementing timely updates to the software. Be it a new version of an operating system/underlying frameworks or critical security patches, we prevent the accumulation of technical debt and ensure zero downtime across existing apps.


Usually, SaaS solutions reside in scalable cloud environments that offer easy integration with other software. Unlike on-premises deployment, this approach does not require additional hardware to sustain growing loads. Instead, it is possible to allocate more resources, scaling an application up and down on demand.


Software as a service can help small and medium businesses to save money, as it does not require investing in expensive hardware or licenses upfront. The same is true for vendors themselves, as they can host the SaaS offering on a third-party cloud platform and pay only for the resources they utilize.
