Gilzor provides offshore web development for companies that need custom websites, web applications, and broader digital products without building the entire engineering function internally.

The company works with startups, SMBs, and product teams, with technologies including React, Next.js, TypeScript, Node.js, Python, PostgreSQL, AWS, Docker, and Kubernetes. Gilzor operates from Warsaw and Limassol while supporting companies across the US market, making its distributed model relevant to Boston teams comfortable managing product development remotely.

SumatoSoft combines a Boston headquarters with a primary development center in Warsaw, creating one of the clearer local-to-offshore delivery structures on this list. Most of its production team is based in Poland, while the company maintains client-facing operations at One Boston Place.

Its web engineering work covers custom web applications, SaaS products, enterprise systems, MVPs, modernization, UI/UX, testing, and back-end development. SumatoSoft supports outsourcing, outstaffing, and dedicated-team arrangements, so Boston companies can hand over a complete project or add offshore engineers to an existing product organization.

Scopic operates from Marlborough, Massachusetts and supports projects through a global remote workforce spanning the US, Europe, Latin America, and APAC. That distributed structure suits Boston-area organizations looking for external engineering capacity without restricting recruitment to the local market.

Its web practice covers custom web applications, SaaS products, existing application maintenance, UI/UX, back-end systems, cloud work, and related software engineering. Scopic also offers dedicated-team and outsourcing arrangements with fixed-price and hourly engagement options, giving companies several ways to structure offshore development.

Trigent Software is headquartered in Southborough, Massachusetts and operates a major delivery location in Bangalore, India. This structure gives Boston-area companies access to a Massachusetts-based provider while allowing engineering work to be handled through an offshore development operation.

Its work spans product engineering, custom software, SaaS applications, cloud projects, AI, data, testing, and modernization. Trigent also helps businesses create and scale engineering centers in India, making it relevant to companies that want something larger than a small outsourced project team.

Deerhold is headquartered in Boston and supports clients through engineering resources in the US, Nepal, Japan, and other locations. The company explicitly offers both offshore and onsite development, supported by teams working across different time zones.

Its capabilities extend from software design and application development to data work and mobile solutions.

Appsierra directly markets offshore engineering services to Boston companies. Its Boston delivery model uses managed development pods based in India, with schedules adjusted to provide overlap with Eastern Time. There is no Boston office, which the company states clearly, so the relationship is structured as remote offshore delivery rather than local staffing.

For web projects, Appsierra provides full-stack engineers working with React, Node.js, TypeScript, Python, Java, and .NET. It also offers cloud-native applications, SaaS platforms, APIs, progressive web applications, legacy modernization, QA, DevOps, and data engineering.

Kanda Software provides custom software and product engineering through teams supported by US-based delivery managers. The company uses a distributed development model that allows engineering resources and skill sets to scale as product requirements change.

Its experience includes healthcare, life sciences, security, analytics, and other areas common in the Boston technology market. Kanda is therefore more relevant to organizations developing substantial applications and digital products than businesses simply looking for a basic corporate website. Its model can also work for existing product teams that need external engineers without transferring every aspect of product ownership.

Innowise provides offshore custom web development and wider software engineering services for businesses that need an external development organization. Web work can include tailored applications, platform development, modernization, front-end and back-end engineering, and related project management.

The broader service portfolio also covers integrations, AI, managed support, CRM, and ERP work, which can matter when a web application has to connect with existing enterprise systems.

Avenga maintains an office at 125 High Street in Boston while operating engineering locations across Europe and other international markets. The company handles web software engineering as part of a wider product engineering portfolio, which gives Boston organizations access to distributed teams without giving up a local corporate presence.

Its web work covers enterprise portals, SaaS products, e-commerce systems, internal applications, progressive web apps, and cross-platform applications. Front-end technologies include React, Angular, Vue.js, Svelte, and Next.js, while back-end capabilities include Node.js, Java, .NET, Python, and Go.

Auriga is headquartered in the Boston area and operates multiple development centers across different time zones. The company describes itself as a custom software engineering and outsourcing provider, with established options for remote engineering teams and offshore development structures.
