Description
CodeTrain serves as an educational platform tailored for engineers engaged in shipping AI projects, especially when they find it challenging to articulate every feature they have developed. By transforming a question, repository, or onboarding assignment into concise lessons comprised of two to six actionable steps grounded in actual code, it allows learners to actively engage by typing each line. While the tutor is responsible for designing the steps, executing the code, providing feedback on each attempt, and breaking down the steps further when a learner encounters difficulties rather than simply providing answers, this interactive approach fosters deeper understanding. The free tier facilitates Python execution directly in the browser via Pyodide, ensuring that no data is transferred off the user's machine, making it exceptionally cost-effective to operate. For more complex tasks, server-side sandboxes are utilized to manage shell and toolchain lessons. The infrastructure is supported by FastAPI hosted on Fly.io for the control plane, with a static front-end deployed on Cloudflare Pages, while authentication is managed through Clerk, and billing is processed via Stripe. Tutoring capabilities are primarily powered by Claude models, but the platform also accommodates custom keys for Anthropic, Bedrock, Vertex, OpenAI-compatible endpoints, and Ollama, allowing teams to leverage their existing infrastructure for inference. This flexibility ensures that organizations can optimize their learning tools while maintaining control over their resources.
Description
WalletWallet is the simplest API for generating Apple Wallet and Google Wallet passes. One POST returns a signed Apple .pkpass, a Save to Google Wallet link, and a hosted page that shows the right Add button per device. There is no Apple developer account, certificate, or Google issuer setup: WalletWallet runs the signing and issuer infrastructure for both platforms.
One PUT updates a live pass and pushes the change to both wallets (Apple via APNs, Google via server-side push), and a DELETE revokes it on both when a membership lapses or a ticket is refunded. That lifecycle covers most pass use cases: loyalty cards for coffee shops and gyms, membership cards for libraries and studios, event and cinema tickets, season passes, coupons, and gift cards.
It works whether a developer integrates it directly or a coding agent builds the integration: the docs ship in agent-readable form at walletwallet.dev/llms.txt, so pointing Claude, Codex, or another agent at the API is enough to wire it into a CRM, booking system, or storefront. Supports all barcode formats (QR, PDF417, Aztec, Code 128), fully customizable fields, colors, logos, thumbnails, and strip images, plus a visual editor that exports the exact API call. Built on Cloudflare Workers, so pass generation runs close to the caller worldwide.
One pass covers both Apple and Google and counts once. The free tier includes 1,000 passes a month with no credit card. Pro is $39 a month for 100,000 passes, custom branding, and higher limits.
