Choosing well
Which coding features do I need?
Choose by the work you want help with: compare code completion, chat assistance, coding agents, codebase indexing, and terminal access.
Check supported IDEs as well, since the right fit depends on where you write code.
Which platforms does it need to run on?
Check the tool's supported platforms before choosing, especially if you plan to use it on Android.
The platform comparisons cover Linux, macOS, Windows, web, extensions, and APIs. They do not establish Android support for an individual tool.
What will it cost, and is there a free plan?
Compare the free plan, starting paid price, and trial terms rather than relying on a pricing label alone.
For example, Amazon Q has a free plan and lists paid access from $3 per user per month, with a 60-day trial. Gemini CLI lists a free plan.
Can I read or change the code?
Check whether the assistant is open source if access to its code matters to you.
Aider is listed as open source. A free plan does not by itself mean that a tool is open source.
