Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aider

  • Requires comfort working in a terminal rather than a graphical IDE
  • Has no hosted or managed version, so users must supply and pay for their own LLM API access separately
  • Depends heavily on the chosen underlying model's quality, so results vary by which LLM is configured
  • Lacks a built-in autonomous multi-step task runner comparable to agent-style products

Vite

  • Does not support Node.js built-in polyfills, requiring manual configuration for CommonJS libraries
  • File watching fails on Windows Subsystem for Linux 2 in certain conditions
  • Smaller ecosystem and community compared to webpack
  • Ampersands in Windows project paths cause module resolution failures

Answered from the vendors’ own pages

Aider: Is Aider free to use?

Aider itself is free and open source, released under the Apache 2.0 license. Users must separately supply and pay for API access to the LLM they choose to use with it.

Source
Vite: Does Vite support CommonJS dependencies?

Vite automatically converts CommonJS dependencies to ES modules during pre-bundling using esbuild, but it does not support Node.js built-in polyfills. For projects requiring Node builtins, additional configuration may be needed.

Source
Aider: Which LLMs can I use with Aider?

Aider connects to OpenAI, Anthropic, Gemini, GROQ, DeepSeek, Ollama, Azure, Cohere, xAI, GitHub Copilot, Vertex AI, Amazon Bedrock, OpenRouter and most other LLM providers via API keys.

Source
Vite: Can Vite work offline?

Vite requires internet for initial dependency pre-bundling with esbuild. Once dependencies are pre-bundled and cached, development can continue with local file serving, but full offline development is not supported.

Source
Aider: Can I use Aider for free without paying for an LLM API?

Yes, Aider can be used at no cost through OpenRouter's free model access (subject to daily usage limits) or Google's Gemini 2.5 Pro Exp, which the docs note performs well without a paid API key.

Source
Vite: What are Vite's system requirements on Windows?

Vite can run on Windows, but WSL2 users may experience file watching issues where Vite cannot detect file changes in certain conditions. Windows users with project paths containing ampersands may encounter module resolution failures with npm.

Source
Aider: How does Aider handle version control?

Aider automatically stages and commits each change it makes to a connected git repository, generating a descriptive commit message for every edit so changes stay reviewable and reversible.

Source
Vite: Does Vite support TypeScript, JSX, and CSS out of the box?

Yes. Vite natively supports TypeScript, JSX, CSS, and WebAssembly without additional configuration needed for basic use.
