A collection of free, open-source tools and interactive playgrounds I've built to solve real problems. From temporal parsers to data transformers, each tool is designed with developers in mind.
Calculate monthly payments, total interest, and loan costs for property purchases in Singapore. Supports promotional rates, visualizes payment schedules, and compares scenarios. Takes into account TDSR limits and minimum down payment requirements.
Calculate progressive payment schedules for Singapore new launch properties (BTO, EC, new condos). See stage-by-stage payments, interest during construction, and final monthly payments after TOP and completion.
Interactive playground for parsing ISO 8601, RFC 3339, and IXDTF temporal expressions. Visualize token anatomy with color-coded lexer output and explore structured AST. Powered by @taskade/temporal-parser.
All tools are available as embeddable widgets. Click "Get Embed Code" on any tool above to get the iframe code, or browse all embeddable versions on the dedicated embeds page.
