Yesterday's Top Launches: 5 Tools from February 19, 2026
Five new developer tools and an amusing reaction game debuted yesterday, focusing on streamlining specific workflows.
Yesterday brought an interesting mix of tools to the digital landscape, especially for developers and productivity seekers. While we saw everything from a quirky reaction game to essential infrastructure software, the common thread was a focus on streamlining specific workflows. Here’s a closer look at the five new developer tools and apps that debuted on February 19, 2026.
Reflex Rooster
If you're looking for a quick, silly way to test your reflexes, Reflex Rooster might be your new favorite time-waster. It's a web-based game where your reaction speed is everything. The premise is simple: a chicken screams, and you tap. You can play solo to practice, try to set a high score in an endless streak mode, or race against others in multiplayer.
It tracks your stats like XP, rank, and reaction times, and doles out badges for achievements. It’s clearly aimed at casual gamers or maybe teams looking for a lighthearted competitive activity. There's no complex setup or download required since it runs in a browser, and the price is right—it's completely free. It’s not going to revolutionize your workday, but it’s a fun, browser-based distraction.
Calendarly
How many times have you picked up your phone just to check what's next on your calendar, only to unlock it, find the app, and open it? Calendarly attempts to cut out those steps by turning your calendar into a live Lock Screen wallpaper. Your schedule is visible the moment you wake your device, updating automatically as meetings start and end.
This is a paid mobile app built for anyone who lives and dies by their calendar. The immediate benefit is obvious: at-a-glance schedule awareness without any active effort. The success of this app will likely hinge on its battery efficiency and how well it integrates with various calendar providers. If it’s done well, it could be a genuine convenience for busy professionals who are tired of app-switching.
ClawMetry
For developers building with AI agents, monitoring their performance and cost can be a black box. ClawMetry steps in as a free, open-source dashboard designed to provide transparency. It offers real-time tracking of crucial metrics like token costs, the status of cron jobs, the activity of sub-agents, and memory usage.
This is a desktop-focused tool that seems tailored for developers and teams who are scaling their use of AI. By being open-source, it offers a level of customization and trust that proprietary solutions might not. If you're deploying multiple agents and need to keep a close eye on your budget and system health without adding another expensive SaaS subscription, ClawMetry is definitely worth a look. It solves a very specific but growing pain point in modern development.
OpenFlowKit
Creating clean, professional diagrams is often a tedious process, especially for engineers and architects who value precision. OpenFlowKit is a free, open-source diagram engine built to address this. It’s positioned as a tool for craft-conscious teams, offering AI-powered creation, support for Mermaid.js syntax, one-click export to Figma, and intelligent auto-layout capabilities.
Built with React Flow, Mermaid.js, and TypeScript, this web-based tool seems particularly powerful. The integration of AI could significantly speed up the initial diagramming process, while the export feature bridges the gap between technical documentation and design collaboration. For any team that regularly produces system architectures, flowcharts, or network diagrams, OpenFlowKit presents a compelling, cost-effective alternative to paid tools.
Cencurity
As companies integrate LLMs and AI agents more deeply into their products, securing the data sent to and from these models becomes critical. Cencurity is a security gateway that acts as a proxy for this traffic. It actively detects, masks, and blocks sensitive data (like PII) and risky code patterns in real-time, all while maintaining detailed audit logs.
This is infrastructure-level software, available via web and API, and it’s free. It’s aimed squarely at developers and organizations that need to enforce security policies around their AI integrations without building this complex filtering and logging capability in-house. The value proposition is strong: preventing accidental data leaks and ensuring compliance without sacrificing functionality. In an era of increasing data privacy concerns, a tool like Cencurity feels almost essential.
