The real monthly cost breakdown of Cursor ($20) vs GitHub Copilot ($10), plus two free BYOK alternatives for solo developers watching every dollar.

Cursor costs $20 per month, GitHub Copilot costs $10, and both score 57% crowd approval in the arena. But solo developers on a tight budget have two more options the marketing pages never mention: Cline and Aider, both free and open source, where the only bill is your own API tokens.
The budget verdict
GitHub Copilot Pro at $10/month delivers unlimited completions and solid chat. Cursor at $20 adds smarter agents. But Cline ($0 software, $30-80/month inference) scores 71% crowd approval and runs inside Cursor, giving you both for less.
The $10 vs $20 showdown #
GitHub Copilot Pro starts at $10 per month with $15 in AI Credits and unlimited code completions. Cursor Pro costs $20 per month (or $16 on annual billing) with a $20 frontier-model credit pool. Both include multi-model access to Claude, GPT, and Gemini families.
The pricing math looks simple until you use agent mode. Copilot's $15 credit allowance evaporates fast with autonomous tasks. Cursor's Composer 2.5 is credit-unlimited on every paid plan, scoring 79.8% on SWE-Bench Multilingual (effectively tied with Claude Opus 4.7 at 80.5%). For agent-heavy workflows, Cursor delivers more capability per dollar despite the higher sticker price.

CursorClineAider## The free alternatives nobody talks about Cline and Aider cost nothing. The software is Apache 2.0, fully auditable, no subscription required. You pay only for the LLM inference you actually use.
Cline scores 71% crowd approval (the highest in this comparison) with 58K GitHub stars and 5.8M installs. It runs as a VS Code extension, works inside Cursor, and supports every major model provider: Anthropic, OpenAI, Google, AWS Bedrock, Groq, DeepSeek, or free local models via Ollama. Typical professional use runs $30-80 per month in API tokens, often less than a $200 IDE subscription while staying fully under your control.
Aider targets terminal-first developers. With 44K GitHub stars and 6.8M PyPI installs, it routes roughly 15 billion tokens per week through its infrastructure. Every AI edit lands as a clean auto-commit you can diff or revert. The same $30-80 monthly API cost applies for heavy use.

Which one actually saves money #
The cheapest path depends on how you code:
Tab completion primary, occasional chat: GitHub Copilot at $10. The unlimited completions alone justify the price, and the free tier (2,000 completions, 50 chat requests monthly) works for hobbyists.
Agent-first workflows, multi-model switching: Cursor at $20. Composer 2.5's credit-unlimited policy means agent tasks do not drain your budget. The Agents Window runs parallel sessions across local and cloud targets.
Maximum control, minimum fixed cost: Cline at $0 software plus API tokens. Running it inside Cursor gives you both tab completion and agentic capabilities. Many power users report this combo delivers better value than any single subscription.
Terminal native, git discipline required: Aider at $0 plus tokens. The auto-commit workflow is unmatched, 88% of the code in its latest release was written by Aider itself.

The verdict #
- Solo developers on the tightest budget should start with GitHub Copilot's free tier (2,000 completions monthly) or Copilot Pro at $10 for unlimited completions.
- Developers who want agent capabilities without overspending should consider Cline inside Cursor: $20 for the IDE plus $30-80 in API tokens beats Cursor Ultra at $200 while offering full model freedom.
- The crowd speaks clearly: Cline's 71% approval rate suggests the BYOK model resonates with cost-conscious developers. Cursor and Copilot tie at 57%.
