Pricing
FreemiumBolt.new uses a token-based Freemium model. The Free tier provides 1 million tokens per month (with a 300,000 token daily cap), unlimited databases, website hosting with up to 333K web requests/month, and supports both public and private projects. Bolt branding appears on Free-tier websites. Pro costs $25/month (or less with annual billing) and includes no daily token limit, starting at 10M tokens/month, no Bolt branding, custom domain support, private site sharing, 100MB file uploads, up to 1M web requests, SEO boosting, expanded database capacity, choice of database provider, AI image editing, and unused token rollover for up to one additional month. The Teams plan is $30/user/month and adds centralized billing, team-level access management, granular admin controls, design system knowledge with per-package prompts, and private NPM registry support. Enterprise pricing is custom and includes everything in Pro plus SSO (Okta, Azure AD, SAML), SOC 2 Type II compliance, BYOK deployment on AWS or Azure, HIPAA/FedRAMP-ready infrastructure, a dedicated customer success manager, private Slack support channel, custom SLAs, hands-on onboarding, and unlimited token allocations without overage surprises.
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.

Bolt.new Pros & Cons

Pros

  • Second-fastest-growing software product in history after ChatGPT — proven at massive scale
  • WebContainers moat: only tool to run a full Node.js stack natively in the browser with zero setup
  • Full-stack by default — databases, auth, APIs, and hosting all included without third-party accounts
  • Broadest enterprise trust: 75% Fortune 500 adoption, SOC 2 Type II, BYOK AWS/Azure deployment
  • Free tier is genuinely useful — 1M tokens/month with unlimited databases and live hosting
  • Figma import and design system support makes it ideal for agency and product team workflows

Cons

  • Token-based pricing can be unpredictable — large projects consume tokens rapidly, pushing users to Pro or Teams quickly
  • Token limits reset monthly; unused Pro tokens roll over only one month
  • Bolt branding appears on websites built on the Free plan (removed on paid plans)
  • Strongly web-focused — not suitable for native mobile apps, desktop software, or backend-only services
  • Complex apps with intricate business logic may still require manual code review and iteration
  • Dependent on AI model providers (Anthropic, OpenAI) — model access disruptions can affect availability
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
