Reactive Playground vs API Guard

Reactive Playground is a visual learning app for reactive programming. Instead of reading operator definitions only, you can play with marble timelines directly. Pick a category, open an operator, move events around, edit their values, clone items, remove them, or turn them into errors and completed events. The output updates live so you can understand what each operator really does. Explore operator categories such as: Transforming Filtering Combining Error Handling Utility Each playground shows a source timeline, an output timeline, a short explanation, and a code-style example. It is useful for learning ReactiveX concepts, reviewing operators, or quickly refreshing how a stream behaves before using it in code. Reactive Playground is made for developers, students, and anyone learning Rx-style reactive programming.

Octoshield watches your code repositories for exposed API credentials, then helps you respond before a leaked key turns into a security incident or runaway cloud bill. Built for developers, indie hackers and small teams, Octoshield connects to your source code workspace, lets you choose the repositories you want to monitor, and scans pushed commits for high-risk secrets such as OpenAI, Stripe and AWS keys. Why developers use Octoshield: - Monitor selected public and private repositories - Scan new pushes for exposed credentials and risky secrets - Receive critical leak alerts when a matching key is found - Review commit history and alert status from your iPhone - Track billing velocity signals for connected provider credentials - Keep credential storage optional and manage saved keys in-app - Use the free plan for one repository or upgrade for unlimited repository monitoring A single accidental commit can be enough for automated scanners to find and exploit a production key. Octoshield gives you a focused mobile command center for the moments when speed matters: see what was exposed, where it happened, and what needs attention next. Octoshield is designed for practical developer security, not noisy dashboards. Connect your code workspace, choose your repositories, and keep an eye on the credentials that protect your products, customers and cloud budget. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your App Store account settings.
