GitHub's contribution graph actively gamifies over-commitment and open-source communities have no tooling to detect when contributors are heading toward burnout — a problem so serious it generated a 1,789-upvote GitHub issue with 202 comments. ContribPulse analyzes commit frequency, PR review load, issue response time, and after-hours activity across a repository to surface contributors showing classic burnout signals: spiking then crashing commit rates, increasingly terse responses, or long unbroken streaks without weekends off.

TermAlias is a lightweight daemon and terminal wrapper that lets users assign sticky custom labels to terminal tabs independently of the window title string. When AI coding tools like gemini-cli constantly rewrite the title to show progress, TermAlias displays both the user nickname and the live tool title in a split format, so context is never lost. It works with GNOME Terminal, Konsole, and any VTE-based emulator without replacing the terminal itself.

I want to build an app called "PasteGuard".
## The Problem
Developers are accidentally pasting personal or sensitive data into cloud AI tools, creating compliance and privacy risks with no frictionless prevention layer — a recurring concern in AWS Bedrock data retention discussions.
## Target Audience
Developers, lawyers, and knowledge workers who use cloud AI tools daily and work with sensitive or proprietary information
## Core Idea
A clipboard proxy that detects and redacts PII and secrets before they reach cloud AI tools.
Developers and knowledge workers are accidentally pasting personal data, API keys, and confidential business information into ChatGPT, Claude, and Gemini, creating serious compliance and privacy risks that accumulate silently over time. PasteGuard intercepts clipboard content destined for browser-based AI tools, runs a fast local scan for patterns matching emails, phone numbers, API keys, SSNs, and credit card numbers, and presents a one-second confirmation dialog with detected items highlighted before allowing the paste. It works entirely locally with no cloud component, making it safe for the compliance-conscious users who need it most.

01Developer Tool
ScopeSync
Paste a list of Slack OAuth scopes and install them all in one click instead of one agonizing dropdown at a time.
Pain point
Configuring a Slack app with ~30 OAuth scopes requires clicking through a dropdown 30 separate times with no bulk-add option, wasting significant developer time on pure UI friction with no workaround.
Who needs it
Developers building Slack apps and integrations
Monetization
Free browser extension with a $5 one-time tip jar; upsell a $9/month SaaS dashboard that stores and syncs scope manifests across team members

## Core Idea
Paste a list of Slack OAuth scopes and install them all in one click instead of one agonizing dropdown at a time.
ScopeSync is a browser extension that detects the Slack app OAuth permissions page and injects a bulk-import textarea. Developers paste their full list of required scopes (e.g. copied from a README or schema file) and the extension automatically selects and adds all of them in sequence. It also exports the current scope set back to a plain text list for documentation.

TodoSync
A sync reliability layer for Todoist that guarantees tasks created via Siri or notifications actually appear across all your devices.
Pain point
Todoist users report multi-year sync failures between iOS and desktop where completing tasks from notifications doesn't register and Siri-created tasks disappear silently, causing real productivity loss.
Who needs it
Power Todoist users who rely on Siri integration and notification-based task completion and have experienced data loss

## Core Idea
A sync reliability layer for Todoist that guarantees tasks created via Siri or notifications actually appear across all your devices.
Todoist users report multi-year sync failures between iOS and desktop — tasks completed from notifications stay marked incomplete on desktop, Siri-created tasks silently vanish, and the only fix is manually reopening the app. TodoSync runs as a lightweight background agent that monitors your Todoist account via the API, detects orphaned or unsynced tasks by comparing device states, and forces reconciliation with intelligent conflict resolution. It also provides an audit log of every sync event so users can finally see why their tasks are disappearing.

SubScan
A single command that discovers and queries DNS records for all subdomains of a domain automatically.
Pain point
Developers and sysadmins want a dig-like tool that automatically enumerates all subdomains rather than querying them one at a time — a gap explicitly raised on Software Recommendations Stack Exchange with no satisfactory solution found.
Who needs it
DevOps engineers, security researchers, and sysadmins who regularly need to audit DNS records for entire domains
Monetization
Open-source CLI with a $9/month hosted API for CI/CD integration and rate-limit-free lookups

## Target Audience

## Core Idea
A single command that discovers and queries DNS records for all subdomains of a domain automatically.
The standard dig utility requires querying each subdomain individually with no native way to enumerate them automatically, creating tedious repetitive work for developers and sysadmins doing reconnaissance or infrastructure auditing. SubScan combines passive subdomain discovery via Certificate Transparency logs, DNS brute-forcing from a curated wordlist, and active DNS resolution into a single fast CLI tool with structured JSON or table output. It handles wildcard detection, rate limiting, and resolver rotation out of the box — the thing dig should have been for this use case.
