Remain Software is a software change management vendor based in Nieuwegein, the Netherlands. According to the site, it has been developing change management software for IBM Midrange Systems since 1992. Its core product, TD/OMS, targets the IBM i / AS/400 / iSeries / IBM System i market and is designed to control the full lifecycle of enterprise software, from incidents, fixes, testing, and acceptance through to release into production. Another mentioned capability is the Gravity REST API and its interactive API documentation.
TD/OMS focuses on software change management rather than general-purpose code hosting or CI/CD. Its repository resides on IBM System i and can track software changes from incident to fix, while also covering stages such as testing, acceptance, and deployment to production. It also handles validation, user sign-offs, and change documentation, making it suitable for enterprises with strong requirements around process governance, audit trails, and release control.
The Gravity API supports REST, and its documentation page provides an interactive tool for making REST calls, allowing users to adjust input parameters and view HTTP responses. The API follows the Swagger OpenAPI specification. The page also offers downloads of the specification source and the ability to generate client code in different programming languages on demand, which is useful for system integration and automation development.
The site does not disclose official pricing, licensing models, or payment methods. It only mentions that a free one-month trial of Gravity is available. Therefore, it appears to offer at least a trial option, while commercial quotes will most likely need to be confirmed by contacting the vendor or a channel partner.
The advantages are that Remain Software has a long history in the IBM i software change management space and has established a distribution partnership with Solutions First in the United States and Canada, which has many years of experience in SCM implementation and training. TD/OMS covers a complete process flow and is well suited to rigorous change control for core systems in traditional enterprises. The drawbacks are that public information is limited: it does not specify whether the product is open source, whether it can be self-hosted, which languages or frameworks are supported, or provide details on SLAs, pricing, and integrations.
It is better suited to enterprise development teams, release management teams, and IT infrastructure service providers that still run mission-critical business systems within the IBM i / System i / AS/400 ecosystem. If a team needs a general-purpose cloud-native DevOps platform, the available information is insufficient to show that it covers those needs.
The site does not provide information about access from mainland China, regional nodes, or compliance, so actual availability is unknown.
