Why it matters

What does 3 months of architectural drift actually cost you?

When you code with LLMs that suffer amnesia after every session, you aren’t building an app. You’re building a house of cards. The worst part? It looks fine. Until the day it doesn’t. And by then, the decay runs deeper than you want to admit.

You start a new project

Building with AI on any other codebase

AI invents plausible-but-wrong patterns

AI code contradicts itself — and keeps going

More energy spent reviewing AI code than time saved writing it

A codebase that ‘works’ but you’re too scared to touch

Building with AI on a self-correcting foundation

You start a new session. The AI picks up exactly where you left off.

You check the plan, not every line. 3 minutes, not 3 hours

Six months in, you can still open any file and understand it.

You’re not afraid of your own codebase

Start again

Decision-making compounds

Ship. Again.

Meet Durabl

The only codebase engineered for howAI coding tools actually work

Other boilerplates hand you a static template and hope for the best. Durabl ships with the persistent context your AI needs to build correctly — today and 6 months from now.

Production-ready codebase

Start with every hard decision already made

Built on React Router. Three concepts: loader, action, component. That's the entire model. Fewer abstractions. Fewer things AI can get wrong. Full SSR, file-based routing, and typed data loading — built on web standards like Request and Response, not proprietary APIs. Deploy anywhere, no vendor lock-in.

User Interface

  • 100+ components — from primitives to full page sections — giving you production-ready screens you can ship on day 1.
  • One composition pattern everywhere. AI learns the pattern — and replicates it on every page.
  • Examples & prop signatures documented for every component. AI finds your existing components instead of rebuilding HTML from scratch.
  • Accessible. Keyboard-navigable. Light/dark themeable with no extra config.

Persistent AI context

Give your AI the correct context. Every session. Every task.

AI forgets your app — and you can’t fit your entire codebase into a context window. Durabl ships a knowledge system with a single entry point. Your AI knows what to read before planning, what to understand before building, and where to find the relevant docs. So you can build fast, knowing your code will work.

AI instruction files

AI instruction files (CONTEXT.md) act as your AI's entry point into your project. Whatever AI tool you use, simply add one line to your config file pointing at CONTEXT.md, and your AI has all the context it needs to keep your code consistent.

Documentation files

Documentation files store the rules, rationale, and trade-offs that span your codebase. Your AI coding tool consults the relevant docs before modifying a file.

Inline comments

Inline comments embed the logic behind hyper-local decisions in the code itself. So instead of “improving” your decisions, AI preserves the behavior you prefer.

Built-in AI skills

AI that plans, tests, and self-corrects.

By default, AI assistants only do what you type. No testing. Missed edge cases. And fixing bugs is all on you. Building with Durabl is different. When you create new features, AI will load the right skills for each phase of work. Automatically.

You don’t need to configure a thing.

What is an AI skill in Durabl?

Better input. Better output. Zero extra work.

Durabl’s skills are Markdown files that give your AI expert-level instructions for a specific task. Readable, editable, and version-controlled. Giving you senior–dev standard prompting — even if you’re not a prompt engineer.

Durabl’s growing library of AI skills includes:

Plan

Define intended state → map current-to-intended → surface hidden assumptions → validate with developer

Implement

Execute plan → check off items → review code → write tests

Validate

Run ESLint → type check → format → commit → push → wait for CI

Bug-squash

On any failure, re-enter the full cycle: re-plan → re-implement → re-validate

Expand docs

Write decisions back into your docs → your AI gets smarter with every feature

Idempotent by design

Sessions crash.
Your work never does.

Most AI tools treat your conversations as disposable. With Durabl, every plan is stored as a file in your repo. So if your laptop dies or you close the wrong window, nothing is lost. Start a new session, say "continue," and the AI picks up exactly where you left off. No re-explaining. No lost context. No starting over.

AI skills don't run in sequence — they compose.

Plan

Done

Define intended state → map current-intended → surface hidden assumptions → validate with developer

Implement

Done

Execute plan → check off items → review code → write tests

Validate

Running

Run ESLint → type check → format → commit → push → wait for CI

Done

Self-correcting workflows for new features

Your AI loads the planning skill, surfaces every hidden assumption, and waits for your sign-off — before writing a line of code. Once you approve, implementation and validation skills take over automatically. No manual handoffs.

Plan

Done

Define intended state → map current-intended → validate with developer

Implement

Done

Execute plan → check off items → review code → write tests

Validate

Fail

Run ESLint → type check → format → fail

Check failed - bug squash activates

Re-plan

Diagnose failure → update plan

Re-implement

Apply fix → update plan

Re-validate

Run checks again

All checks pass - exit loop

Done

Debugging that doesn’t stop until the result is clean

When a check fails — and it will — the bug-squashing skill kicks in, cycling back through planning, implementation, and validation. It keeps going until every check passes. You don't intervene. You don't re-explain. It just works.

Creator Bio

Hey, I’m André.

I’ve built more than 100 software applications over 20+ years, working with clients including Monster Energy and NBC News.

Over the last 2 years, I kept seeing the same failure pattern play out. AI generates code fast. But it has no memory between sessions. Codebases degrade. Entropy compounds until the whole thing becomes unmaintainable.

Correctness, not speed, is now the biggest bottleneck.

Every boilerplate I looked at was solving the old problem: save time on setup. So I built a codebase that solves the new one: keeping code correct as AI builds at velocity.

I use it for every new project. It's the foundation I wish I'd had 2 years ago.

Testimonials

What devs say about Durabl

“As a seasoned developer, I’ve spent countless hours wrestling with infrastructure, best practices, and endless decisions. It’s exhausting. With Durabl, I had a production-ready app and staging environment set up in 10 minutes. Unreal. Where has this been all my life?”

Joshua Zinkovsky

Software Engineer, MyForeverBooks

“I used to spend a lot of time setting up everything, the environments, deploying, choosing the tools that I wanted to use. With Durabl, I can spend time building and not setting up. I’m really excited to use it more, to build new products and to launch it fast.”

Kirill Lapshev

Software Engineer, Buddiez

“Durabl is a super valuable tool! It saved me hours of setup time, letting me focus on the actual development instead of infrastructure headaches.”

Joey Jiron

Software Engineer, Microsoft

“Durabl saved me a lot of time and work that I would have spent designing components that could be reused. Now I can focus more on the software architecture and commercial aspects of our products.”

Hatem Soliman

@h4temsoliman

“I had an excellent experience using Durabl, especially as someone new to working with React Router. The comprehensive documentation that comes with it made getting up to speed easy.”

A boilerplate is a starting state for a software project. It encodes decisions — architecture, tooling, patterns, conventions — so you don’t start from zero. The value is: decisions already made, correctly.
