What is Flo?
Flo is a CLI (command-line interface) tool that automatically catches errors in your codebase and provides solutions by scanning your entire codebase. The tool uses a Langchain functions agent powered by OpenAI's GPT models to evaluate error messages and search through your files to identify faulty code or logic, then tells you how to fix it directly in your terminal without any copy-pasting required.
Key features include automatic error monitoring of processes you run (like 'npm run dev' or 'node index.js'), the ability to pass error messages directly to Flo for analysis, GPT-4 support for better solutions, optional web search capabilities via Serp API for errors that need external information, VS Code extension integration for Next.js apps, customizable terminal output colors via theme settings, and the ability to filter out warnings to focus only on errors. The tool lives inside your codebase, so it doesn't need you to provide context or copy-paste long error messages.
Flo is designed for developers who frequently encounter coding errors and want to eliminate the frustration of debugging. It's particularly useful for developers working with Node.js scripts, Next.js applications, and anyone using VS Code who wants automated error detection. The tool is open-source, configurable, and works across multiple development environments.
The tool eliminates context loss that occurs when trying to solve errors with traditional methods like ChatGPT, Google, or Phind, since you don't need to manually copy-paste error logs or code. Errors are caught automatically and resolved by the AI agent in under 30 seconds, increasing developer momentum by reducing friction in figuring out what's wrong with your code.
Flo pricing
Pricing model: Free
Flo is open source and free to install, but requires users to provide their own API keys. You need an OpenAI API key (required) to use GPT-3.5-turbo or GPT-4, and an optional Serp API key for web search capabilities. Both API keys are paid services that users must obtain and configure separately using the 'flocli configure' command. There is no free tier included with Flo itself since it uses your own API keys.
Flo pros
- Automatically catches errors without manual copy-pasting
- Scans entire codebase to find faulty code
- Provides solutions directly in terminal

- Works with Node.js scripts and Next.js apps
- VS Code extension available for Next.js
- Supports GPT-4 for better solutions
- Optional web search via Serp API
- Can filter out warnings to focus on errors
- Open source and configurable
- Easy npm installation globally
- Customizable terminal output colors
- Resolves errors in under 30 seconds

Flo cons
- Requires OpenAI API key (paid, not free)
- Requires Serp API key for web search (optional but paid)
- Early stage project with file reading failures
- Relative file paths can cause ENOENT errors
- Needs absolute paths for reliable file access
- VS Code extension only works with Next.js
- May fail when monitoring client-side warnings in Next.js
- Flags must be explicitly set to true (not automatic)
Frequently asked questions about Flo
How do I install Flo?
You can install Flo globally using npm with the command 'npm install -g flocli' or simply 'npm i flocli'. After installation, you need to run 'flocli configure' to set up your API keys before using it.
What API keys do I need to use Flo?
Flo requires an OpenAI API key (mandatory) to power the GPT models. You also need an optional Serp API key if you want to enable web search capabilities for error solutions. You configure these using 'flocli configure' which will prompt you to enter both keys.
Why does Flo sometimes fail to read files?
Flo can fail with ENOENT errors when using relative file paths. The tool works best with absolute paths like 'Users/myname/app/package.json' rather than relative paths like 'package.json'. This is because Flo uses the file paths from error stack traces which are typically absolute. Always try using absolute paths to prevent file reading failures.
Is Flo free to use?
Flo itself is open source and free to install via npm, but you need to provide your own paid OpenAI API key to use it. The Serp API key for web search is optional but also requires a paid account. There is no included free tier since Flo uses your own API keys for scalability and security.
How does Flo solve errors differently from ChatGPT or Google?
Flo eliminates context loss because it lives in your codebase and doesn't require manual copy-pasting of error logs or code. The AI agent intelligently searches through specific files suspected to cause the error and examines only relevant code, so there are rarely context window issues. Errors are resolved automatically in under 30 seconds without any 'prompt tennis'.
