By Agentic Weekly, operated independently from Texas, US · Last updated (America/Chicago) · How we work
Open-source AI pair programming in your terminal that maps your codebase and connects to almost any LLM, including local models.
Aider's site says it lets you pair program with LLMs from the terminal, builds a map of your entire codebase to help on larger projects, and can connect to almost any LLM including local models. The GitHub repository lists the Apache-2.0 license. The newest release tag we saw is v0.86.3.dev (Feb 12, 2026).
What it does well: Apache-2.0 open source; Model-agnostic; Free to use.
Where it falls short: Latest release tag we saw is from Feb 2026, so check for newer activity; You pay the model provider separately; The site's recommended-model list names older models; Our test was one small task on a local 3B model; it does not show behaviour with hosted models or larger jobs.
Latest version we cover: none recorded (Feb 12, 2026). Vendor: Aider-AI (open-source project).
Developers who live in the terminal and want git-friendly AI edits
People who want to pick their own model or run local models
Aider: Partly verified. No pricing page. The tool is free; model usage costs depend on the provider you connect. Evidence: Tested (smoke test, 2026-10-25, local 3B model (Qwen2.5-3B)).
Before you switch, note what we could not verify about Aider:
Tested (smoke test, 2026-10-25, local Qwen2.5-3B-Instruct, not vendor models)
