Pricing
FreemiumAmp offers three pricing tiers. The free ad-supported tier includes Amp Tab autocomplete, core agent access with no hard token caps, thread sharing, and the Librarian codebase sub-agent. Sponsored suggestions appear in non-code contexts (dashboard, docs lookups). No credit card required. Smart Mode at $20/month removes ads, opts out of data sharing and model training, unlocks Oracle Mode at full reasoning depth, and provides priority model routing during peak demand. As of August 2026, Smart Mode also allows routing usage through a linked ChatGPT or X Premium+ subscription at no extra per-token cost. A $200/month tier covers higher-volume individual usage. For teams, Amp offers workspace management with centralized billing, admin controls, shared threads and workflows, and enterprise-grade security. Enterprise pricing is custom and adds SOC 2 compliance, zero data retention, and dedicated support.
FreeAider itself is completely free and open source under the Apache 2.0 license, with no subscription, tiers, or usage limits imposed by the project. Costs come entirely from the LLM provider a developer chooses to connect: for example, Anthropic, OpenAI, or DeepSeek API usage is billed directly by that provider at its own per-token rates, or developers can run local models through Ollama at no cost at all. Because there is no Aider-specific markup or platform fee, effective cost is determined by model choice and usage volume rather than by Aider itself.

Amp

Amp Pros & Cons

Pros

  • Ad-supported free tier is the only genuinely unlimited free tier among major coding agents — no hard token caps, no daily limits
  • Multi-model routing across Claude, GPT, and other frontier models per task — not locked to a single AI provider
  • The Librarian uniquely enables live search across all public GitHub and private repos without loading files manually
  • Sourcegraph's code intelligence infrastructure gives Amp deeper codebase context than most terminal agents
  • Available in CLI plus every major editor (VS Code, Cursor, Windsurf, JetBrains, Zed, Neovim) — true editor-agnostic flexibility
  • 40,000+ teams adopted within the first months of 2026 — rapid validation of product-market fit after spin-out

Cons

  • Ad-supported free tier means sponsored suggestions appear in non-code contexts like the dashboard and docs lookups
  • No open-source code — closed-source commercial product unlike Cline, Goose, or OpenHands
  • Smart Mode (no data sharing) requires a paid subscription — free tier users' interactions inform Amp's training pipeline
  • As of August 2026 Amp subscriptions are $20 and $200/month — pricing is now similar to Claude Code and Cursor, eliminating its former pay-as-you-go-only advantage
  • CLI-first design means limited visual IDE experience compared to Cursor or Windsurf — no GUI file explorer or diff viewer built in
  • Spun out from Sourcegraph in December 2025 — organizational independence is new and long-term stability is still being established
Aider

Aider Pros & Cons

Pros

  • Completely free and open source, with no platform markup on top of LLM provider API costs
  • Deep git-native workflow makes every AI change individually reviewable, diffable, and reversible
  • Model-agnostic support for 100+ LLM providers, including local models, avoids vendor lock-in
  • Efficient repo mapping keeps large codebases manageable without dumping entire files into context
  • Transparent, actively maintained public leaderboard helps developers pick the best-performing model for real coding tasks

Cons

  • Terminal-only interface has a learning curve for developers used to GUI-based tools like Cursor or Copilot
  • No bundled AI access; users must bring their own API keys and manage separate billing with LLM providers
  • Deliberately not a fully autonomous agent, staying one step behind tools like Devin that run unsupervised for longer stretches
  • No official enterprise support tier or SLA, since the project is community-maintained open source
