Aider vs Continue.dev

Where you work matters most. Aider assumes you're comfortable in a terminal and that your editor is something separate. You switch to a terminal tab, describe what you want, and Aider modifies files on disk. Continue.dev assumes you're already in VS Code or JetBrains and never want to leave. You highlight code, hit a shortcut, and get suggestions inline. This isn't a minor UX preference; it shapes how you structure your thinking about a coding problem.

Git integration depth. Both tools work with git, but Aider treats git as a core primitive. Every change it makes gets committed automatically with a descriptive message. You can undo any AI change with a simple git revert. Continue.dev interacts with git through your IDE's native tooling, and its PR-focused features add agents that run checks on pull requests. Aider is git-native at the edit level; Continue.dev is git-aware at the review level.

Autocomplete changes everything. Aider has no autocomplete. You type a request, it edits files. Continue.dev's tab completion runs constantly while you code, suggesting the next few lines based on context. For developers who rely on autocomplete as part of their flow, this is a dealbreaker in Continue.dev's favor.

Community and ecosystem. Aider has a passionate following among terminal-centric developers and consistently performs well on coding benchmarks like SWE-bench. Its repo-mapping feature (compressing large codebases into context-friendly summaries) is genuinely clever. Continue.dev has broader reach because IDE extensions have a lower barrier to entry, and the team has built integrations with GitHub, Sentry, and other dev tools.

Configuration philosophy. Aider is a single binary with command-line flags. Continue.dev uses a JSON config file that can get complex once you're setting up multiple model providers, custom slash commands, and context sources. More power, more knobs to turn.

Aider and Continue.dev both want to make you faster with AI, but they come at the problem from completely different angles. Aider is a terminal tool, plain and simple. You install it with pip, point it at a git repo, and start talking to it in your terminal. It reads your codebase, makes edits across files, and auto-commits with sensible messages. That's the whole pitch: AI pair programming in the place where many developers already live.

Continue.dev started life as a VS Code and JetBrains extension, and that's still its core identity even as the team has expanded into CLI and PR automation territory. It gives you inline autocomplete as you type, a chat panel for asking questions, an edit mode for targeted changes, and a full Agent mode that can plan and execute multi-step tasks. The company behind it (Continue Dev, Inc.) also offers paid hosted plans for teams that don't want to manage their own API keys.

Both tools are open source under Apache 2.0 and both let you bring your own model provider. But the day-to-day experience of using them couldn't be more different. Aider is a conversation in your terminal. Continue.dev is a set of panels and overlays woven into your editor. The right choice depends less on features and more on where you prefer to think.

Both tools are free to use if you bring your own API keys. That's the headline, and for most individual developers it's the whole story. Install either one, plug in your Anthropic or OpenAI key, and start coding. Your costs are whatever the model provider charges per token.

Where it gets interesting is Continue.dev's paid tiers. Their Starter plan offers hosted model access at $3 per million tokens, which eliminates the need to sign up with model providers directly. The Team plan at $20/seat/month adds admin controls, usage dashboards, and centralized configuration. For a company with 10 developers, that's $200/month for managed AI coding assistance across everyone's IDE, which is cheaper than most per-seat alternatives.

Aider has no paid tier at all. Zero. It's a tool you install and run. The only cost is your LLM API bill. For a solo developer running Claude through Anthropic's API, expect $10-40/month depending on how heavily you use it. Running local models through Ollama brings that to literally zero.

The hidden cost with both tools is context window usage. Aider's repo-mapping feature is efficient, but heavy multi-file edits on large repos can burn through tokens fast. Continue.dev's autocomplete runs continuously, which adds up if you're on a metered API plan.

If you're a backend developer who lives in tmux, uses vim or neovim, and thinks of your editor as just another terminal pane, Aider is your tool. It fits naturally into a terminal-centric workflow and doesn't ask you to change how you work.

If you're a full-stack developer in VS Code who uses the integrated terminal, the file explorer, and the git panel all day, Continue.dev will feel like a natural extension of what you already do. The autocomplete alone might justify the switch from a basic Copilot setup.

If you manage a team and want automated code review on PRs, Continue.dev's agent features and team plans give you something Aider simply doesn't offer. Aider is a solo tool. Continue.dev has team features.

If you run local models on your own hardware because you care about privacy or cost, both tools work, but Aider's simpler setup makes it slightly easier to get Ollama models running.
