SimplAIfree tier, from $5/mo▲589Hey HN, I've been building SimplAI for the past several months — it's a platform for building, testing, and deploying LLM-powered agents and multi-step workflows. The problem I kept running into: spinning up an AI agent pipeline means stitching together prompt management, tool calling, memory, evals, and deployment — often from scratch every time. SimplAI tries to be the layer that handles all of that so you can focus on what your agent actually does. What it does: - Visual + code-first workflow builder for chaining LLM calls, tools, and APIs - Built-in prompt versioning and A/B testing…

Hi I'm Dan from Elodin, making an open source real-time capable flight software simulation. For AI Grand Prix contestants, the wait for the Round 1 virtual qualifier simulation has been grueling. If you’re competing, check out our simulation harness to tide you over, built to match the published competition constraints and message format. It runs against real Betaflight, which we learned requires at least 1000 sensor samples per second to run real-time correctly. The competition warranted introducing a new feature to generate the camera sensor directly in the simulation loop. Typically…

Games in general and multiplayer games have been a big part of what my friends do together (not just digital; sports, board + card games) And it moved to online games as more of us moved to other places and party games became our go-to Love jackbox and gaming couch (that I discovered here on HN) I saw the vibej.am for this year and I couldn't think of a good enough idea till about the 3rd week but here I am! This is a game made for me and my friends and it's also very inspired by what I thought the PS3 6-axis controller would be when I first heart about it Thanks for reading this and I hope…
