Helpful Tools.
Supporting Utilities.
Real Impact.
Driven by efficiency and built on purpose, this is where bold thinking meets thoughtful execution.
A single tool for all of your AWS Cloud Management tooling,
ARCHITECT UTILITIES
The AWS reference tools you tab back to ten times a day
Built into the same console where you manage your accounts. No ads, no stale data, no context-switching away from your work.
WHO THIS IS FOR
Built for cloud architects who need answers fast
In-context tools that eliminate the bookmark soup and let you stay focused on the work that matters.
🏗️
Cloud Architects
Designing a VPC and need a CIDR sanity check? Use the Subnet Calculator without leaving Quiverstone.
🌐
Network Engineers
Building security group rules around AWS service IP ranges? Get live, parsed views of AWS's published ranges.
🗺️
Multi-Region Teams
Planning a new region rollout? Check which AWS services are actually available where before you commit.
SUBNET CALCULATOR
CIDR planning for VPC and subnet design
AWS-aware subnet calculator that respects AWS's /28 minimum subnet size and reserves the 5 addresses AWS reserves per subnet. Visualize the IP address breakdown — total, usable, reserved.
IPv4 + IPv6 subnet planning
AWS-specific validation (minimum /28, reserved addresses)
Visual breakdown of total, usable, and reserved IPs
Export as CloudFormation or Terraform
📡
AWS IP Lists
Live, parsed view of AWS's published service IP ranges from the canonical ip-ranges.json file.
Filter by service (S3, CloudFront, EC2, etc.)
Filter by region
Build security group allowlists
Configure on-prem firewall rules
Updates automatically when AWS publishes new ranges
🌍
Region Capabilities
Quick lookup of which AWS services are available in which regions — including service-level details.
Multi-region deployment planning
Validate customer "we want X in Y region" requests
Evaluate new regions as they launch
Service-level availability, not just yes/no
A GROWING TOOLKIT
Why bookmark soup doesn’t work
In-context tools that eliminate the bookmark soup and let you stay focused on the work that matters.
The Utilities surface is intentionally extensible. More architect tools on the roadmap.
🔗
Context Switching
Engineers tab out of their work tool to do a 30-second calculation, then forget what they were doing. Productivity death by a thousand cuts.
💰
Paywalls & Ads
The good free tools live on five different sketchy sites with paywalls, ads, and crypto-mining scripts. Not acceptable for production work.
📚
Scattered AWS Docs
AWS docs for service-region availability are scattered across product pages. Finding an answer takes 10 minutes when it should take 10 seconds.
