OpenClaw + Aider: Pair Aider for Local Coding with an OpenClaw Bot for Always-On Chat

Why Pair Aider with OpenClaw?

Aider lives in your terminal. You point it at a repo, ask it to add a feature or fix a bug, and it edits your files and writes the commits. It's superb for hands-on coding, but it stops the moment you close the terminal.

OpenClaw lives on the messaging platforms your team and users already use. Telegram, Discord, WhatsApp, and web chat are always on, always reachable, and don't care whether your laptop is open. It's superb for an AI that needs to stay available for other people.

Together they cover the full stack of how a developer actually works: Aider for the hour-long coding session at the terminal, OpenClaw for the “hey can you check this for me” questions that come in over chat all day.

Workflow Patterns That Work

1. Coding agent (Aider) + chat agent (OpenClaw) on the same model

Pick one frontier model — Claude Sonnet 4.6, GPT-5.4, or DeepSeek V4 Pro is the usual sweet spot — and use the same provider for both tools. Aider gets your hands-on coding sessions; OpenClaw answers questions over chat using the same model behavior.

2. Aider for code, OpenClaw for everything else

Aider stays in the repo. OpenClaw handles the rest: research, scratch reasoning, code review of pasted snippets, daily summaries, on-call notifications, customer support. The split keeps Aider laser-focused on file edits and OpenClaw open to anything.

3. OpenClaw triggers Aider

Use the OpenClaw shell-exec or skills system to fire Aider runs from a Telegram or Discord message: “@bot add a debounce to the search input.” OpenClaw runs aider --message "..." in the repo, posts the diff back into chat. This works best on a self-hosted OpenClaw with shell access enabled.

Step 1: Install Aider Locally

# Recommended: pipx for an isolated install
pipx install aider-chat

# Or with pip
pip install aider-chat

# Sanity check
aider --version

Step 2: Pick a Shared Model and Provider

The simplest path is to use OpenRouter for both Aider and OpenClaw. One key, one bill, dozens of models, and trivial to switch between Claude, GPT, DeepSeek V4, Gemini.

Set your OpenRouter key once:

# In your shell profile (~/.zshrc, ~/.bashrc)
export OPENROUTER_API_KEY="sk-or-..."

Run Aider against any OpenRouter model:

# Claude Sonnet 4.6 via OpenRouter
aider --model openrouter/anthropic/claude-sonnet-4.6

# DeepSeek V4 Pro via OpenRouter
aider --model openrouter/deepseek/deepseek-v4-pro

Step 3: Configure OpenClaw with the Same Provider

In your OpenClaw openclaw.json:

{
  "models": {
    "providers": {
      "openrouter": {
        "apiKey": "sk-or-..."
      }
    }
  },
  "agents": {
    "defaults": {
      "model": {
        "primary": "openrouter/anthropic/claude-sonnet-4.6"
      }
    }
  }
}

Or, on OpenClaw Launch, just pick the same model in the configurator dropdown — AI credits are included so you don't need an OpenRouter key for the chat side at all.

Step 4 (Optional): Let OpenClaw Run Aider for You

On a self-hosted OpenClaw with shell-exec enabled, you can wire a skill that takes a chat message and runs Aider against your repo:

# .openclaw/skills/aider-edit.sh
#!/usr/bin/env bash
set -euo pipefail
cd "$AIDER_REPO_PATH"
aider --yes --message "$1" 2>&1 | tail -200

Register it as an OpenClaw skill, then on Telegram or Discord:

@bot aider-edit "add error handling to fetchUser()"

The bot will run Aider against the repo, capture the diff and any test output, and post it back into the chat. Useful when you're away from your terminal but want a quick code change while you keep your hands free.

Cost Notes

• Aider — Free, open source. You only pay your model provider.
• OpenClaw self-hosted — Free, open source. You pay hosting + model.
• OpenClaw Launch — $3 first month, then $6/mo (Lite) or $20/mo (Pro), AI credits included. You don't pay OpenRouter for the chat side.

A common combo: free Aider locally on your own OpenRouter key, OpenClaw Launch for the always-on chat side with included credits. Total: ~$6–20/mo plus your Aider token usage.

Aider vs OpenClaw — Which Should You Use?

• Aider for hands-on terminal coding. Open repo, dictate change, watch diffs land, commit. Best when you're actively editing.
• OpenClaw for always-on AI on messaging platforms. Reply to users on Telegram, run scheduled tasks, answer questions in Discord. Best when something needs to stay live.
• Both if you do real engineering work AND want a chat AI for yourself or your team/users.
