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.

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.

Last week I launched the tools section 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.

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 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 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.
