aider Alternatives
Other options in the same category as aider (Coding), sorted by free plan and Chinese support:
Chinese support: Full support
For long-form writing and content creation: Pro at US$20/month is worth it. Free-tier users should be prepared — once the rolling quota runs out, you have to wait, and there's no Claude Code. For team use, annual billing is recommended to save 20%.
Chinese support: Not supported
For coders: start with the free Hobby plan, upgrade to Pro at US$20/month once you're coding daily; for team use, annual billing is recommended for 20% savings. But the English-only interface is a real drawback — anyone who can't work with English at all should consider something else.
Chinese support: Not supported
Students: Pro is free after certification, no reason not to use it. General developers: Free version with 2,000 completions to get started, upgrade to Pro for US$10/month after writing every day. However, it's a fact that free and student plans can only use Auto-select models, so if you mind, you can pay for it.
Chinese support: Not supported
If you're looking for "Windsurf": it no longer exists — go to devin.ai and look for Devin Desktop. The free tier's unlimited Tab completion is worth trying, but the uncertainty during this rebrand transition is real — confirm exactly which product you're buying before you subscribe.
Chinese support: Not supported
Zero experience, don't want to touch environment setup: try the free plan's small quota first. Daily use: Core billed annually at US$20/month is the best value. But there's no mid-tier plan between US$25 and US$100, so moderate users can get stuck in an awkward spot.
Chinese support: Not supported
For a one-off small prototype, and you're already using Vercel: the free plan is enough. For daily iteration, or wanting to deploy independently of Vercel: 7 messages a day will quickly become a bottleneck, and you'll need to budget for the paid tier.
Chinese support: Not supported
Non-engineers building an MVP or a quick site: try the free plan's 1 million tokens first. For steady use: Pro at US$25/month is reasonable, and the 2-month token rollover is a plus. But the daily 300,000 cap and the all-English interface are hurdles — anyone in a hurry should be mentally prepared.
Chinese support: Partial support
Developers try out models and create prototypes: use the free quota directly, no need to think about it. Before going into production, calculate the excess fee rate carefully, as Search and Maps have different prices, don't get them mixed up.
Chinese support: Not supported
Security team needing pen-testing: the open-source version is free to self-host, using your own LLM key. Need cloud hosting and support: Pro at US$29/seat, with a 7-day trial. But the price increases are real -- factor that into long-term budgeting.
Chinese support: Not supported
Developers testing AI-agent sandboxes get 500 free credits to start; production-environment billing is transparent, pay-as-you-go, no hidden costs. But Chinese support is none, and there's no subscription discount -- you'll need to calculate high-volume costs yourself.
Chinese support: Not supported
If you're already using Claude Code or Codex and want visualization plus multi-agent collaboration, the US$6.99 one-time purchase is low-risk and worth trying. But seat availability and pricing info have long been non-transparent, so if that bothers you, wait until the official site clarifies things before buying — there's no free version to try first.
Chinese support: Not supported
For non-engineers who want to quickly turn ideas into usable apps, trying the free version first is a good idea. The Pro version, which costs US$25 per year, is the most cost-effective option. Students should also apply for a 50% discount. However, the credit consumption is not transparent, and the free quota is limited. Before heavy iteration, be prepared for potential over-budget costs.
Chinese support: Not supported
Mac + Apple Silicon users who want to create native desktop applications can start with a free 120-credit trial plus 14-day verification, and then decide on Pro for US$20. However, non-Mac users currently cannot use it, and the credit cost is also unclear, so it's best to estimate usage on the official website before subscribing.
Chinese support: Partial support
Developers can access multiple models at once: the free version offers 50 trials per day. For stable usage, Pay-as-you-go is the most flexible option, but the 5.5% handling fee is a hidden cost, so calculate carefully before using extensively.
Chinese support: Partial support
For developers who want the fastest inference speed: try the free API key first, then switch to the Batch API to cut costs in half once volume grows. But the free tier's rate limits aren't transparent, so have a backup plan for production.
Chinese support: Not supported
Developers running open-source generation models: Pay-as-you-go is the most flexible, with FLUX Dev at US$0.025/image being very cheap. However, there is no free version, so it's recommended to test with a small amount before subscribing. Private models are also charged when idle, so remember to turn them off after use.
Chinese support: Not supported
Developers who need web scraping and structured extraction get a free quota to try first, but it's only a one-time 500 or 250 — it doesn't reset once used up. For steady usage, choose Developer at US$25/month; for heavy volume, go up to Pro at US$149. Be sure to ask about the commercial-use terms before subscribing.
Chinese support: Partial support
For personal learning and non-commercial use: the free plan's feature breadth is one of the widest in its category. For work or commercial output: the free plan can't be used commercially, so you need to go straight to Pro at US$14.99. The education plan at US$5.99 is the lowest tier for those who qualify.
Chinese support: Not supported
Solo developer, low PR volume: the free plan's 1 summary/hour is enough, and there's no repo limit. Team needing line-by-line review, or frequent PRs: 1/hour will hit the wall immediately, and Pro at US$30 is the real starting point. Open-source maintainers, remember to apply for the dedicated free plan.
Chinese support: Not supported
The free plan suits slowly working on a small project, but you have to accept the pace of 5 credits a day — no rushing it. If you want to get it done in one go, you'll need to look at Starter at US$20. Rule of thumb: if your project can be finalized within a dozen or so revisions, the free plan gets you through a month just fine.
Chinese support: Not supported
For learning or small internal tools, the free tier's 100 actions/day plus not counting failed actions makes real usability higher than it looks on paper. For a proper public launch with your own domain, you'll need Pro at US$25.
先等一下——aider 也不是沒有優點
For engineers doing AI pair programming in the terminal, it's a free and stable choice — pair it with a local model and you save even the API cost. But you'll need to bring your own LLM key and manage costs yourself. For non-engineers or people who want a graphical interface, this tool's barrier is too high — don't force it.
