ミガロ．（MIGARO） is a Japanese company focused on development tools and custom development for modernizing IBM i (AS/400) environments. Its website is not positioned around a general-purpose low-code platform; instead, its core theme is GUI, web, and mobile modernization for IBM i mission-critical systems. It offers three main tool lines—Valence, Delphi/400, and Cobos4i (formerly SP4i)—along with technical support, training, case studies, and outsourced system development.
Valence is a low-code development tool for building IBM i web applications. It can create input, update, and query applications through three steps: defining data sources, Widgets, and applications. It supports dashboards, charts, tables, forms, maps, KPIs, responsive mobile interfaces, and can use RPG to add complex logic. Version 6.3 introduces Valence AI Assistant, which can help generate data sources using Japanese natural language. According to the site, only metadata such as file names, field names, and descriptions is sent to the cloud AI service.
Delphi/400 is a visual development tool that adapts Delphi for IBM i. It supports Windows, macOS, iOS, and Android, uses Object Pascal, and can call existing RPG/COBOL/CL and DB2 for i assets. It can also connect to SQL Server, Oracle, MySQL, and SQLite.
Cobos4i/SP4i is suitable for teams that want to preserve their RPG/COBOL skills. It allows developers to design flexible web interfaces in HTML, while the tool generates RPG/COBOL skeleton code. It also supports mobile, Web APIs, Office/CSV output, and related capabilities.
The website does not publish specific pricing, so this appears to follow a typical commercial licensing / quote-based model. It offers information requests, free trial versions, free online seminars, and paid training courses. Valence AI Assistant is described as being included in the standard Valence license and available after upgrading to version 6.3.
Its main strength is extremely clear positioning: it is well suited to modernizing legacy IBM i systems, refreshing 5250 screens, and reusing RPG/COBOL assets. It also has a relatively complete Japan-based support, FAQ, tips, training, and custom development ecosystem.
The limitations are that pricing is not transparent, the product ecosystem is relatively closed, and adoption may be challenging for Chinese or overseas users. Although the AI feature emphasizes that actual business data is not transmitted, it still involves cloud services and large language models, so enterprises should conduct their own compliance review.
It is best suited for manufacturing, wholesale and retail, logistics, and service-sector companies that still run substantial IBM i/AS400 workloads, as well as Japanese companies or Japan-market teams that want to build web apps, mobile apps, BI dashboards, or customer portals without rewriting core business logic.
Access from mainland China and supported payment methods are not specified in the main content, so they should be considered unknown. If procurement is constrained by language, support, or network limitations, alternatives to compare include IBM Rational Developer for i, LANSA, Mendix, OutSystems, GeneXus, or self-built Java/.NET/PHP solutions.
