01 — The tools
Small, sharp, tested.
Each tool does one job properly. No frameworks to learn, no cloud account required.
GOtests
bundle-phobia-cli
Check npm dependency sizes concurrently from your terminal. Answers "how much is this costing my bundle" without leaving the shell.
RSnative
iam-policy-visualizer
Parse AWS IAM JSON policies and render the effective blast radius as a Mermaid diagram. Fast native binary.
GOtests
tz-meeting-scheduler

04 — Questions
Before you buy.
What exactly do I get?
Source code for the repositories in your tier, delivered digitally and immediately after payment. Each project includes its own README with build and usage instructions, and the test suites where they exist.
Is this a subscription?
No. All three tiers are one-time purchases with free lifetime updates. There is nothing to cancel.
What do I need to run these?
Go 1.21+ for the Go tools, a stable Rust toolchain for the visualiser, Node 18+ for the TypeScript and web projects, and Python 3.11+ for the automations and backend. Nothing else.
Can I use this in commercial work?
Yes. You can use, modify and ship the code in your own projects, including client work. You may not resell or redistribute the source itself as a template or competing product. See the licence terms in the footer for the full wording.
Which tier should I pick?
If you want a handful of useful tools and something to learn from, the $99 Developer Toolkit. If you want the widest surface area of real code across the most languages, plus support, take the $299 Complete Bundle.
What if it isn't what I expected?
Refunds are governed by the refund policy linked in the footer. Read it before purchasing — it sets out the conditions and window clearly.
Stop rebuilding the same stack.
Read real code and ship this weekend.
