The Challenge

Context

When you deliver an MVP, development is only half the work. The other half is the feedback phase. The client discovers the product, tests the features, and reports everything that needs adjusting. It's a necessary step on every project. And on every project, it's the most chaotic one.

The problem

The scenario is always the same:

  • 30-line WhatsApp messages with feedback thrown together, mixing bugs, suggestions, and color preferences
  • phone screenshots with no link to the page in question
  • "the button doesn't work" without specifying which button, on which page
  • feedback scattered across Slack, email, and voice messages
  • no clear priority between a blocking bug and a cosmetic detail

For each piece of feedback, you have to find the right page, figure out what the client means, rephrase it as a technical task, and fix it. That interpretation work sometimes takes longer than the fix itself.

It's not that clients give bad feedback. They just don't have the right tool to give it properly.

What was at stake

On a 10-day delivery, every hour spent deciphering a WhatsApp message is an hour that doesn't go into the product. Rather than keep dealing with this problem on every project, I decided to build the tool that solves it.

The Solution

Overview

Faster Fixes lets clients leave feedback directly on the website they're testing. A widget integrates into the application: the client clicks on the element that's causing issues, writes their comment, and all the technical context is captured automatically in the background. On the developer side, each piece of feedback arrives structured and actionable, ready to be fixed.

Key features

Contextual feedback in one click

The client doesn't need to install or configure anything. They click on the element that bothers them, leave their comment, and that's it. The system automatically captures a screenshot, the page URL, browser information, and the exact element that was selected. No more "the thing on the top right doesn't work" — the feedback comes with all the context needed.

Centralized dashboard

All feedback is collected in one place. Each item is linked to its page, its element, and its screenshot. You can filter by status, prioritize, and track progress. WhatsApp back-and-forth is replaced by a clear, organized workflow.

AI-assisted fixes

Each piece of feedback can be exported as a structured report containing everything an AI coding tool needs to understand the problem and fix it. The developer grabs the report, passes it to their coding assistant, and the fix is applied in minutes. In some cases, the process can be fully automated: feedback is fetched, fixed, and submitted for review with no manual intervention.

Direct integration with development tools

Faster Fixes integrates directly into modern development environments (Claude Code, Cursor, Windsurf). The developer can ask their coding assistant to fetch new feedback, understand the context, apply the fix, and mark the feedback as resolved. No browser, no copy-pasting, no leaving the terminal.

The Process

The project came from a simple observation: after delivering several MVPs, the feedback phase was consistently where everything slowed down. Not because of the clients, but because there was no tool designed for that specific moment in the project.

Faster Fixes was built in one week, in March 2026. One week because the problem was well understood, the scope was deliberately limited to the essentials, and the tech stack was second nature.

Since then, the tool is plugged into every new client project from day one. Clients use it naturally during the iteration phase, and the results are immediate: clear, contextualized feedback, treatable one by one. What used to take hours of back-and-forth messages now gets resolved in a few clicks.

The project is fully open source. The code is public and available for anyone to inspect. It's a transparency choice that's consistent with how I work with clients: full access to everything, no black box.

Results & Impact

What was delivered

In one week of development:

  • a widget that can be embedded on any website in a few lines of code
  • automatic capture of full context (screenshot, page, browser, clicked element)
  • a dashboard to centralize and manage all feedback
  • structured export compatible with AI-assisted development tools
  • direct integration into modern coding environments (Claude Code, Cursor, Windsurf)
  • all of it open source and deployed to production

Results

Faster Fixes is used in production on my own client projects. The feedback phase, which was consistently the slowest and most frustrating part, has become a smooth process. Feedback comes in structured, context is there, and fixes are applied without wasted time.

The product hasn't been marketed publicly yet. The priority was to validate it in the field, with real clients and real projects, before offering it more broadly.

What's next

Faster Fixes is designed to grow into a tool used by other developers and web agencies. Next steps include integrations with project management tools (Linear, Jira), and fully automated workflows where client feedback triggers a fix by an AI coding agent with no human intervention.
