Pricing
FreemiumTrae uses a token/credit-based pricing model introduced in February 2026. The Free plan includes 5,000 autocompletions per month, 10 fast + 50 slow premium model requests, and 1,000 advanced requests — all at no cost, no credit card required. Lite costs $3/month with increased token allocations. Pro costs $10/month with 600 fast premium model requests per month, no queue waiting, and priority access. Pro+ is $30/month, and Ultra is $100/month for power users and heavy agentic workloads. All plans include access to Claude 4.6 Sonnet, GPT-4o, GPT-4.1, Gemini 2.5 Pro, DeepSeek R1, and ByteDance's Doubao models. SOLO Mode and Builder Mode are available on the free plan within monthly quota limits. The Cloud IDE and Trae Work platform are included with all plans.
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.

Trae

Trae Pros & Cons

Pros

  • Most generous free plan of any AI IDE — free access to Claude 4.6 Sonnet, GPT-4o, Gemini 2.5 Pro, and DeepSeek R1 without a credit card
  • 1.6 million+ monthly active users — massive developer adoption proving product-market fit at scale
  • VS Code-compatible — familiar interface, extensions, and keybindings with minimal switching cost
  • SOLO Mode delivers fully autonomous project scaffolding from requirements to deployment — now available as standalone app
  • Pro plan at $10/month is roughly half the cost of Cursor ($20/month) for similar agentic capabilities
  • ByteDance's distribution muscle and model partnerships give Trae access to frontier models competitive with any paid alternative

Cons

  • ByteDance telemetry concern — security researchers confirmed Trae collects detailed telemetry including file paths and hardware identifiers even when toggled off in settings; data retained 5 years with no full opt-out
  • No Linux desktop version — only macOS, Windows, and the Cloud IDE; Linux users limited to browser version
  • Context quality drops on large repos over 50,000 lines compared to Cursor's more mature codebase indexing
  • SOLO Mode still maturing — complex tasks occasionally get stuck in error loops requiring human intervention
  • Credit/token-based pricing introduced February 2026 can be unpredictable for heavy users vs. Cursor's flat $20/month
  • ByteDance geopolitical risk — some enterprises may face procurement restrictions due to TikTok parent company concerns
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
