Platformatic
Platformatic Open Source monorepo
Platformatic enables developers to efficiently develop and run APIs at scale. Historically, API developers have had to repetitively build infrastructure to satisfy foundational requirements, like authentication, authorization, caching, and connection to databases, and have had to manage microservices with technologies such as service mesh or centralized registries. This work is time consuming, undifferentiated, and painstakingly complex. With growing demands of SaaS applications, the amount of API permutations has grown exponentially and has become a development bottleneck. This has led large organizations to create dedicated platform API engineering teams to help teams deliver on business demands. Our goal is to make API development simple: we aim is to remove all friction from the day-to-day of backend developers. Platformatic is a series of Open Source tools to build APIs. -

Prompt with a single prompt object. Returns an object with the response. Prompt with a list of prompt objects. Returns an object with the responses. Make sure to give each prompt a unique name property to prevent overwriting values. Prompt properties can be functions too. Prompt Objects with type set to falsy values are skipped. Prompter function which takes your prompt objects and returns an object with responses. Prompts can be submitted (return, enter) or canceled (esc, abort, ctrl+c, ctrl+d). No property is being defined on the returned response object when a prompt is canceled. -

Pwnagotchi
Deep Reinforcement learning instrumenting bettercap for WiFi pwning
Pwnagotchi is an A2C-based “AI” powered by bettercap and running on a Raspberry Pi Zero W that learns from its surrounding WiFi environment in order to maximize the crackable WPA key material it captures (either through passive sniffing or by performing deauthentication and association attacks). This material is collected on disk as PCAP files containing any form of handshake supported by hashcat, including full and half WPA handshakes as well as PMKIDs. Instead of merely playing Super Mario or Atari games like most reinforcement learning based “AI” (yawn), Pwnagotchi tunes its own parameters over time to get better at pwning WiFi things in the real world environments you expose it to. To give hackers an excuse to learn about reinforcement learning and WiFi networking, and have a reason to get out for more walks. -

RBush
High-performance JavaScript R-tree-based 2D spatial index
RBush is a high-performance JavaScript library for 2D spatial indexing of points and rectangles. It's based on an optimized R-tree data structure with bulk insertion support. Spatial index is a special data structure for points and rectangles that allows you to perform queries like "all items within this bounding box" very efficiently (e.g. hundreds of times faster than looping over all items). It's most commonly used in maps and data visualizations. The demos contain visualization of trees generated from 50k bulk-loaded random points. Open web console to see benchmarks; click on buttons to insert or remove items; click to perform search under the cursor. An optional argument to RBush defines the maximum number of entries in a tree node. 9 (used by default) is a reasonable choice for most applications. Higher value means faster insertion and slower search, and vice versa. -

Smaug
Archive your Twitter/X bookmarks to markdown
Smaug is a developer tool for archiving Twitter (X) bookmarks — and optionally likes — into markdown files in an automated way, offering a simple means of preserving social media content in human-readable, version-controlled text. Named after the treasure-hoarding dragon, it uses the Twitter API (or community tools like the bird CLI) to fetch bookmarked posts and outputs them in markdown, making it easy to back up content for future reference or documentation. Smaug is designed for automation and integration into personal workflows, allowing users to run setup and export jobs from the command line with minimal configuration. It supports configuration through JSON and can be extended or scripted as part of broader personal knowledge management systems. Because the output is plain markdown, it fits well with static site generators and digital gardens — preserving links, text, and metadata in a format that’s both platform-independent and version-friendly. -

Standing Wave 3
Flash ActionScript3 dynamic audio library
Standing Wave 3 is an ActionScript 3 audio library that provides high-level control over the Flash Player’s SampleDataEvent API for streaming audio output. It builds on the foundation of Standing Wave 2 but has been extensively refactored, with its core sample storage and manipulation routines rewritten using Adobe Alchemy for significant performance improvements. Originally derived from the audio engine used in the Noteflight Score Editor, the library allows developers to combine and chain together audio sources, filters, and sequences to create dynamic, real-time sound experiences. Supported audio sources include MP3s, WAV files, and algorithmic generators, while filters enable effects such as echo, equalization, and envelope shaping. The system is flexible enough to handle complex timing sequences of audio, making it suitable for advanced audio applications or interactive projects. -
