Show HN: Zero Waste Cloud – Finds 20-40% savings in AWS/GCP bills and CO2 impact
Show HN (score: 6)Description
TLDR: Sign up -> Connect your AWS/GCP -> Scan -> Save 20-40% of your cloud spend.
My backstory: I've been a CISO and in IT management for a long time and always been frustrated by how much waste I'd find in every environment - idle EC2 instances running 24/7, oversized RDS databases, forgotten storage volumes, test resources that never gets removed. What also bothered me was that nobody was tracking the environmental cost of this waste. Every unused resource burns electricity and contributes to carbon emissions unnecessarily.
What it does:
- Scans AWS accounts using IAM roles or access keys, GCP projects using service account keys
- Identifies specific optimization opportunities: unused EC2/Compute Engine instances, oversized databases, unattached storage, missed reservation opportunities and much more
- Calculates financial savings AND CO₂ reduction for each recommendation using region-specific grid emission factors
- Multi-account/project support
- Generates detailed reports with prioritized recommendations
Technical details: Built with React/TypeScript frontend, Supabase backend. Uses AWS SDK for EC2, RDS, Cost Explorer APIs and GCP's Compute Engine, Cloud SQL, and Cloud Billing APIs. Carbon calculations combine cloud provider PUE data with regional electricity grid emission factors from government sources.
Try it out: The onboarding from creation to your first scan being run is only ~30 seconds. The scanning process is fully automated and typically completes in 5-30 minutes depending on account size of course.
I would genuinely love to get your feedback on it, just came out of beta a few days ago so if there's any bugs around please do let me know =)

Show HN: Control Claude permissions using a cloud-based decision table UI
Show HN: Control Claude permissions using a cloud-based decision table UI We’ve been building visual rule engines (clear interfaces + API endpoints that help map input data to a large number of outcomes) for a while and had the fun idea lately to see what happens when we use our decision table UI with Claude’s PreToolUse hook.<p>The result is a surprisingly useful policy/gating layer– these tables let your team:<p>- Write multi-factor, exception-friendly policies (e.g. deny rm -rf / when --force; allow cleanup only in node_modules; ask on network calls like curl/wget; block kubectl delete or SQL DROP, each with a clear reason)<p>- Roll out policy changes instantly (mid-run, flip a risky operation from allow → ask; the next attempt across devs and agents is gated immediately– no git pull, agent restart, or coordination)<p>- Adopt lightweight governance that is somewhat agent agnostic and survives churn (MCP/skills/etc)- just add columns/rules as new tools and metadata show up<p>- Get a quick central utility to understand which tools are being used, which tools get blocked most often, and why
Show HN: Claude Code Scheduler
Show HN: Claude Code Scheduler I found myself frequently wanting to schedule tasks in Claude Code (both one-time and recurring) so I built a CC plugin to help with that.<p>To install: /plugin marketplace add jshchnz/claude-code-scheduler /plugin install scheduler@claude-code-scheduler<p>Then just tell Claude what you want (some examples):<p>Every Wednesday at 3am find dead code: unused functions, unreachable branches, commented-out code, and unused imports. List by file with line numbers.<p>Schedule a code review every weekday at 9am. Review commits from the last 24 hours, check for bugs, security issues, error handling gaps, and code that needs comments. Summarize with file:line references.
