Signal & Sprocket
Tracertoy · flutter · 2026-07-03An interactive, scrubbable explainer that shows the full journey of a prompt through a simulated LLM request lifecycle — from keystroke to streamed tokens.“you type a prompt, hit send, and the response starts streaming back in under a second. i've always wondered what actually happens in that moment between my keystroke and the tokens coming back, but nobody ever shows you the whole journey.”
Elementatoy · flutter · 2026-07-01A calm alchemy discovery toy where you drag two elements together to fuse them into new ones, unlocking a growing tree of discoveries.“How do you manage data relationships when designing a crafting system? I want a clean way to combine elements into new ones via recipes.”
Pixloomcreative · flutter · 2026-07-01A calm, offline pixel-art studio for drawing sprites on a grid and animating them frame by frame.“What tools do professionals use to create pixel art with animations? I want an approachable editor to draw pixel art and animate it frame by frame.”
Soonerproductivity · flutter · 2026-07-03A recurring-task list that lets you check off a repeating task before its due date and advances the next occurrence correctly.“This app came highly praised but it's missing the one feature that matters most to me: I can't check off a recurring task that's due in the future. If I finish it early I'm just stuck waiting for the due date to come around before I can mark it done. Complete waste of money, and I'm going back to Apple Reminders just to get that basic functionality.”
Tidingsutility · flutter · 2026-07-03A calm RSS/Atom reader that ranks your feeds by freshness and clears them with a single swipe to mark stories read, unread, or starred.“Please keep developing it. I'm worried this RSS reader is abandoned, and I'm missing the swiping gestures to mark stories as read, unread, and starred.”
Markwrighttool · flutter · 2026-07-02A desktop Markdown editor that opens a version-controlled .md file, edits it beside a live rendered preview and document outline, and saves it back in place.“You can't view and edit a markdown file in place, which makes it useless for software engineering where version-controlled MD files need to be regularly used, updated, and saved back into the repository.”
Fallowcreative · flutter · 2026-07-02An alternative contribution graph that scores your commit cadence for sustainability, celebrates rest days instead of erasing them, and flags overwork stretches before they burn you out.“The contribution graph and the statistics on it prominently encourage contributors to over-commit, which is a real well-being issue in open-source communities.”
Reckontool · flutter · 2026-07-02An interactive explorer for the German Tank Problem: capture random serial numbers and watch a frequentist, a Bayesian, and a Monte-Carlo estimator converge on a hidden population's true size.“How many tanks are the Germans actually producing? The Allies had an expensive question and no good way to answer it, and the statisticians beat the spies with serial numbers alone.”
Rubbletoy · godot4 · 2026-07-02A physics demolition sandbox: drop bombs on procedurally-built structures and watch them buckle, shatter, and chain-react into a settling pile of debris.“I built a Chrome extension called Site Bomb. It does exactly one thing: you drop little bombs on a web page and watch it fall apart. No reason, just fun.”
Cadenceproductivity · flutter · 2026-07-02A habit tracker for flexible 'N per week' goals that shows exactly which days you completed each task and lets you edit that history.“It lets you create streaks with a goal of 'N per week' so you don't have to do the task every day, but you can't see which days you completed it. I'll often wonder: did I already mark that done today? Or was it yesterday?”
Pipcompanion · flutter-flame · 2026-07-01A pixel-art desktop companion whose moods and animations react in real time to your focus, idle stretches, and the hour of the day.“One day we had a companion, the next: `Unknown skill: buddy`. Thousands of developers opened their terminals that morning to find an empty status line where their buddy once lived.”
Ligature Labcreative · flutter · 2026-07-01A live playground where you type code and watch character sequences like => != >= -> === resolve into composed ligature glyphs, with toggleable rule sets and your own custom substitution rules.“I would love to see support for ligatures, like Fira Code has, turning character sequences like => != >= -> === into single composed glyphs.”
Quantatoy · react-vite · 2026-07-02A browser physics sandbox that runs a data-oriented Entity-Component-System over thousands of live particles, warped by force fields, with the true per-frame cost read live off a performance HUD.“Can JavaScript really run an Entity-Component-System architecture fast enough to simulate physics on thousands of entities at once?”
Rosettatool · react-vite · 2026-07-01An offline browser workbench that parses coding-agent config files (CLAUDE.md, AGENTS.md, Cursor rules) into one normalized model and translates between the formats live, with section mapping, colored diff, and lint.“CLAUDE.md feels too specific to Claude Code and doesn't work when collaborating with developers using other agents (Codex, Amp, Cursor); devs want a single AGENTS.md that all coding agents understand.”
