Yesterday's Top Launches: 5 Tools from January 21, 2026
Tofu Maps launched as a simple, account-free tool for creating and sharing custom personal maps.
Yesterday brought another interesting mix of tools for developers and creators hitting the scene. For anyone trying to keep their digital toolkit sharp, January 21st, 2026, offered solutions ranging from codebase exploration to funding discovery. Here’s a look at the five new developer tools that launched.
Tofu Maps
If you've ever tried to cobble together a list of locations for a trip or a project, only to have it scattered across notes, bookmarks, and screenshots, Tofu Maps presents a cleaner alternative. The concept is straightforward: it lets you build personal maps, drop pins on places, and share the entire collection via a simple link. There's no account creation required, which lowers the barrier significantly for quick, collaborative planning.
It feels perfectly suited for putting together a weekend itinerary, mapping out filming locations for a video project, or even creating a personal guide to your favorite coffee shops in a new city. Since it's free and web-based, it’s easy to just open a tab and start plotting points without any commitment. The simplicity is its main strength, though you might wonder about the long-term persistence of your maps without an account. For one-off projects or temporary collaborations, however, it seems ideal.
Updatest
Mac users who value a tidy system will likely appreciate what Updatest is doing. It addresses a common nuisance: the fragmented update process. Your apps might come from the Mac App Store, some are installed via Homebrew, others use Sparkle for in-app updates, and then there are those manually downloaded from GitHub. Keeping track of what needs updating across these different channels is a chore.
Updatest consolidates everything into a single dashboard. It not only shows you what’s outdated but also provides security details and allows for bulk updates. A particularly clever feature is its ability to help you "adopt" manually installed applications into Homebrew management, which is a great step toward systematizing a potentially messy setup. As a paid desktop app, it’s clearly targeting users—likely developers and power users—for whom system maintenance is a regular task and who are willing to pay for the convenience of a unified view.
OS Ninja
Diving into a new open source repository can be daunting. The sheer volume of code, documentation, and project history is often overwhelming. OS Ninja attempts to turn this intimidating process into a structured learning experience. It takes a complex repo and transforms it into an interactive, AI-guided journey.
What stands out is the choice of learning styles it offers. You can opt for a Socratic method, where the AI asks probing questions to guide your understanding, or the Feynman technique, which encourages explaining concepts simply. There’s also a more traditional book-like format for linear learners. This flexibility suggests the tool understands that people absorb complex technical information in different ways. It's a free web platform, making it highly accessible for students, new contributors, or even experienced developers exploring an unfamiliar codebase. The success of such a tool would heavily depend on the quality and depth of the AI's guidance.
FlowGenie
The no-code movement continues to expand, and FlowGenie enters the space with a focus on forms and workflows. Its visual, node-based editor will feel familiar to anyone who has used tools like Node-RED or even some automation platforms. You can build logic flows that are triggered by form submissions, run on a schedule, or be activated by external calls.
This kind of tool is incredibly useful for building internal tools, customer onboarding sequences, or any multi-step process that doesn't warrant full-scale software development. The freemium model means you can likely start for free, which is perfect for prototyping a workflow to see if the concept holds water before committing. The real test for platforms like this is often in the execution—how smoothly the nodes connect, the depth of integrations available, and the clarity of the user interface when flows become complex.
21st Fund
Securing funding is a universal challenge for startups, and non-dilutive funding—like grants and credits—is especially attractive as it doesn't require giving up equity. The problem is discovery; these opportunities are often hidden across countless government websites, corporate programs, and institutions. 21st Fund uses AI to scan and surface these opportunities, claiming to have already identified over $100 million in potential capital across more than 20 countries.
For founders, especially those in the early stages, a tool that automates this research could be a significant time-saver. The platform being free to use removes a major barrier, allowing entrepreneurs to focus their energy on applications rather than endless searching. The value proposition hinges entirely on the accuracy, relevance, and freshness of the data the AI provides. If it can reliably uncover opportunities that a founder would otherwise miss, it could become an essential part of the startup toolkit.
