# The Summer of Code

> July and August: no new courses, no launches, just building. A recap of the first week: StackPlan, 140+ free tools, Sitebase, the bootcamp platform, and a new 30 Days of Code course.

I'm calling it **The Summer of Code**.

July and August, for me, are not about planning new courses or launches. I just code what I want. Build things, follow ideas, see where they go.

The first week has been one of the most productive stretches I've ever had. I shipped work across four different projects, all built with Cursor and AI agents. I want to recap it here, partly to share what's new, partly because looking back at a week like this still feels a bit unreal.

Here's what happened.

## StackPlan: a new product, from zero to production in 6 days

The big one. On July 2nd I scaffolded a brand new project. On July 7th it was live in production at [stackplan.dev](https://stackplan.dev).

StackPlan is a deployment stack advisor. You describe your app — through a questionnaire or just a free-text prompt — and it recommends a hosting stack with real cost estimates, based on a curated knowledge base of provider pricing.

In 6 days it got:

- A recommendation engine: a curated pricing knowledge base plus a deterministic cost model, with an LLM rationale layer on top
- A Railway-style interactive canvas where you drag service nodes and watch costs recompute live
- An "engineering dial" that morphs your stack from Duct Tape to Overkill, with animations
- A GitHub repo scanner that detects your stack from manifests and prefills the intake
- 23 case studies of real indie businesses and their stacks (Plausible, Bear Blog, Nomad List, Lichess...)
- A free tools hub: database chooser, serverless-vs-serverful decision tool, Roast My Stack, and more
- Auth, billing with Polar, transactional email with Resend, an admin curation UI, and a daily AI agent that verifies provider prices and files update proposals

The whole thing runs on Cloudflare Workers with the AHA stack: Astro SSR, HTMX, Alpine.js, plus D1 and Drizzle.

## flaviocopes.com: from 90 to 140+ free tools

Last week I [launched the tools section](https://flaviocopes.com/introducing-tools/) with 90 free, browser-only tools for developers. No signup, no ads, your data never leaves your machine.

Since then I kept going. Another 57 tools landed: hosting and deployment utilities, converters, generators, and more browser-only helpers. The collection is now at over 140 tools, all at [flaviocopes.com/tools](https://flaviocopes.com/tools/).

I also cross-linked tools with related blog posts, so if you land on a tutorial about JWTs you'll find the JWT decoder right there, and vice versa.

## Sitebase: repositioned for AI builders

[Sitebase](https://sitebase.dev) is my "features for your website" product: waiting lists, newsletter signups, testimonials, analytics — small embeddable features you drop into any site.

This week I repositioned it around a simple idea: your coding agent should be able to install it for you.

- Agent-legible docs at `/llms.txt` and `/llms-full.txt`
- A remote MCP server, so agents can manage your sites directly
- A public management API with per-workspace API keys
- "Install with your agent" prompt blocks next to every embed snippet
- Outbound webhooks (Zapier, Make, Slack, Discord) and a weekly digest email

It's now deployed to production with a waiting list — and yes, the waiting list on the homepage is a Sitebase widget. Dogfooding from day one.

## The bootcamp platform

The [AI-first Web Development Bootcamp](https://bootcamp.dev) platform got some love too, in preparation for the next cohort, planned for 2027: student progress tracking with per-week badges on the dashboard, downloadable project files on every week page, and theory reading links connecting each week to the relevant tutorials here on the blog.

## A new course: 30 Days of Code

I'm also working on something new: **30 Days of Code**, an email-based course with a companion website.

The idea: the full bootcamp is 16 weeks. This distills the core of it into 30 daily sessions, 1-2 hours each. Every day you get an email, and each day has its own page on the site. Every day has two threads: web development fundamentals (theory plus a hands-on exercise, done without AI) and a daily AI skill (an assignment done with AI).

You learn to code, and you learn to work with AI, at the same time. More on this soon.

## How this was possible

All of this was built with Cursor.

Not "Cursor helped me write some functions". I mean the agents did the heavy lifting: planning, implementing, testing, deploying. My job was direction, review, and taste — deciding what to build, catching what's off, and keeping the quality bar where I want it.

A week like this would have been a quarter of work a couple of years ago. Probably more, because honestly I would have never attempted to build something like StackPlan's interactive canvas by hand.

This is the workflow I teach in the bootcamp, and weeks like this one are why I'm so excited about it.

The Summer of Code is just getting started. More soon.
