Four platform tools for builders

This issue carries four platform tools with a visible surface for comparing, rendering, measuring, or submitting work.

A short field guide

Each section names what the product does, who it serves, and what it gives back. The pages keep the work concrete, from dated vendor rates to frozen launch rankings.

StackTab

StackTab

	StackTab prices a database, auth service, payment provider, and host together. A developer comparing infrastructure gets monthly totals at 1,000, 10,000, and 100,000 users, with each rate dated from the vendor's pricing page. The console shows the selected services and their combined bill. Its catalogue also records plans, rates, and which vendor claims have drifted.

Tearline

Tearline

	Tearline is a custom element that renders HTML as a thermal receipt and exports the result as a PNG. A frontend developer gets a DOM component with six attributes, three methods, and no dependencies. The export runs through four named stages, from flattening the shadow tree to encoding the canvas as a PNG blob. Text and CSS are inlined automatically, while images must already be data URIs.

Toolproof

Toolproof

	Toolproof is a register for AI agent tooling that reads indexes from source and records what they find. A researcher or builder gets dated measurements, methodology notes, badges, and an open read API. The register keeps each index's own name and method, then shows whether it answered or fell behind. Its pages attach figures to the index and capture date that produced them.

ShipWall

ShipWall

ShipWall is a launch board for products built with tools such as Lovable, v0, Bolt, Cursor, Claude Code, or Replit. A builder submits what they made, which tools they used, and how much they edited by hand. The board has ten launch slots per day, assigns a date after review, and freezes the ranking at midnight UTC. Each frozen row keeps its launch date, rank, votes, build method, and hand-editing note.

One issue a week, and one shipped product taken apart every month. What each product does, what it cost to build, what the pipeline behind it looks like, and what the numbers did, read off the repository and the live site, not written from memory. Join the list.
