In their own words
Isomer
Isomer is a free website builder for Singapore government agencies and public healthcare institutions to create static websites without coding. Its Isomer Studio editor lets public officers build, edit, and publish pages with drag-and-drop controls. Publishing supports review requests, approvals, and release of approved changes. Agencies can select page layouts, combine components, and customize colours, logos, and favicons.
Accessibility prompts cover essential fields, while templates and components are designed to support accessible sites. SEO features include predefined headings, generated tables of contents and folder index pages, image alt text, and customizable meta descriptions. Open Government Products builds and manages Isomer. Its team handles hosting, maintenance, support, and compliance with relevant IM8 and Digital Service Standards clauses, and centrally manages security testing and audits. Isomer does not provide website design services or custom layouts. Domain costs and third-party services such as web monitoring may be extra.
