Aider vs Base44

Aider is a terminal tool that pair-programs with you. You tell it what to change, it edits the files, and (here is the part that wins people over) it creates a clean git commit with a descriptive message. Every change is tracked, reviewable, and revertable. No other AI coding tool handles version control this naturally.

Built by Paul Gauthier, it builds a map of your whole repository so it can work on larger codebases. The tradeoff is that it is terminal-only and requires you to bring your own API key, and there is a learning curve to getting the most out of it (knowing which files to add, how to prompt). Development has also slowed: the latest release, v0.86.0, came out in August 2025, and the repository has had no new commits since May 2026, so support for newer models may lag. If you are already comfortable with git and the command line, aider fits into your workflow like a glove. If you want a visual editor experience, look at Cursor or Cline instead.

Base44 takes a different approach from most AI app builders: instead of writing code you can see, it generates complete applications through a chat interface. Describe what you need (“build me a task management app with user auth and Stripe billing”), and it creates the database, UI, backend logic, and authentication. Apps are live immediately with built-in hosting.

Wix acquired Base44 in 2025 for around $80 million, so expect the product to evolve toward the Wix ecosystem over time. The free tier is tight (5 messages per day), but enough to test whether the approach works for your use case. Best for internal tools, simple SaaS MVPs, and founders who want something working today rather than something architecturally perfect.
