Aider vs Bolt — Pricing, Plans, and Verified Costs (2026)
Both Aider and Bolt use custom pricing — request quotes from each to compare.
How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Aider (Per Usage) — Aider bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Bolt (Hybrid) — Bolt is hybrid: a fixed subscription plus metered usage on top. Your real bill moves with volume, not seat count.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Open-source AI pair-programming CLI. Aider runs in your terminal, connects to any LLM via API, edits your codebase, and commits changes to git. Completely free (open source, MIT license) — users pay only for underlying LLM API tokens. Popular with terminal-heavy developers who prefer Unix workflows over GUI editors.
AI-native web development environment from StackBlitz. Prompt in natural language, generate full-stack apps that run in a browser-based WebContainer sandbox with instant preview. Token-metered pricing model — each AI generation consumes tokens from your monthly allocation. Pricing: Free (1M tokens/mo), Pro $25/mo (10M tokens, scales to $50 for 26M and $200 for 120M), Teams $30/user/mo. Annual billing saves up to 28%. Positioned as the fastest way to prototype full-stack apps entirely in the browser — no local setup, no separate hosting.

What each is best for
Aider is worth it if… developers who live in the terminal and want an AI pair programmer without a GUI editor. The git-native workflow (every AI edit becomes a commit) is genuinely differentiated — you get an audit trail for free.
Bolt is worth it if… developers and prototypers who want browser-native, full-stack AI app generation without ever leaving the tab. The WebContainer runtime differentiates it from Lovable and v0 — apps actually execute in the browser, not just render as previews.
Bottom line: Choose based on how you want to pay — Aider is per usage, Bolt is hybrid.
