Selenium

Software Freedom Conservancy

Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point.

WordPad

Microsoft

WordPad is a basic text-editing app you can use to create and edit files, include text with different fonts and colors, insert pictures, and add links to other files. You can use WordPad to open and save text files (.txt), rich text files (.rtf), Word documents (.docx), and OpenDocument text files (.odt). Files in other formats will open as plain text files and might not appear as expected. Some features, like headers, footers, and annotations, aren’t supported in WordPad. If you open a file with these features and then save the file in WordPad, you’ll lose the content in these features. If you want to change such a file, but don’t want to lose the original content, tap or click Save as and save the file with a different name. That way you can make changes to a copy of the file while keeping the content in the original file intact. For more info about what each button does, press and hold the button for a description (or if you’re using a mouse, point to the button).

Contrast Security

Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efﬁciencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.

ReqKey

ReqKey adds API key authentication, usage credits, rate limiting and request analytics to an API you own. Your own middleware makes a single verify call per incoming request: ReqKey validates the caller’s key, deducts a credit from that consumer’s pool, enforces their rate limit, and records the request with status code, latency and location. It never sits in front of your API — no proxy, no gateway, no DNS change — so it adds no hop to your critical path. Validation averages under 5ms. Credits pool per consumer rather than per key, so issuing a customer a second key does not hand them a second quota, and balances stay synced across regions. Also included: shadow limits, controlled overage, reusable plans, low-credit alerts, and per-request logs filterable by endpoint, status, consumer and time range. ReqKey meters and tracks usage — you keep your own billing stack. SDKs for Python, Node.js, Go, Rust, PHP, .NET and Java, with framework adapters for FastAPI, Express, Django, and more.
