Fixer is a lightweight and developer-friendly API service designed to provide real-time and historical foreign exchange rate data for a wide range of global currencies. It aggregates financial data from multiple sources, including institutions like the European Central Bank, to deliver accurate and frequently updated exchange rates. The API supports over 170 currencies and offers multiple endpoints that allow developers to retrieve latest rates, perform currency conversions, and analyze historical trends over time. One of its key strengths is its simplicity, as it uses straightforward RESTful endpoints and JSON responses that can be easily integrated into web or mobile applications. Fixer also supports time-series and fluctuation data, enabling more advanced financial analysis and forecasting use cases. While a free tier is available with some limitations, more advanced features such as higher request limits and additional base currencies are offered through paid plans.

Forem is an open-source platform for building community publishing sites—most famously powering the DEV community—that emphasizes authoring, discoverability, and social features tailored to niche communities. It combines long-form posts, collections, tagging, and following mechanisms with membership controls, moderation tools, and monetization options to let communities grow sustainably. The platform supports rich authoring (markdown, embeds), comment threading, reactions, and community curation so content creators and readers can engage in meaningful discussions rather than transient exchanges. Forem is designed to be portable and extensible: it exposes APIs for ingestion and embeds, theming options for brand alignment, and admin features for content policy, moderation workflows, and analytics. It encourages community governance patterns that let moderators and members participate in shaping norms and surfacing high-quality content.

Foreman is a Procfile-based process manager that mirrors Heroku’s process model, making it easy to run multi-process applications in development and beyond. You declare your app’s processes (web workers, background jobs, schedulers) in a Procfile, and Foreman starts them together, streams multiplexed logs, and manages environment variables from .env files. It handles port assignment and process concurrency, so you can spin up multiple copies of a worker or web server with a single command. Exporters generate native service definitions (e.g., systemd/Upstart/launchd), enabling the same process topology to run under OS service managers in staging or production. Colorized, prefixed logs and simple signals (restart/stop) provide a clear operational experience for polyglot stacks. By codifying your app’s runtime composition, Foreman reduces “works on my machine” friction and keeps local setups close to deployment reality.

FormCreator is a tool for users to quickly and graphically create online web forms. It allows paper forms to rapidly be converted to an online format by users with little or no techinical experience.
