  • Tín dụng: AgentRouter ($200 cho lập trình viên mới), cùng các khoản tặng nhỏ hơn khi đăng ký từ Token Harbor và YepAPI.
  • Tự ghép bộ công cụ: gói miễn phí của Gemini API, Mistral và các mô hình miễn phí luân phiên của OpenRouter dùng được với mọi trình soạn thảo hoặc CLI agent.

Điểm cần lưu ý: gói miễn phí giới hạn mức dùng, tín dụng rồi sẽ hết, và một số nơi đòi thẻ khi đăng ký - bảng bên dưới ghi rõ nơi nào. Sinh viên có bộ ưu đãi riêng ở trang dành cho sinh viên.

  • AgentRouter for most developers: $200 of credit that works with AI-assisted coding tools and LLM routing APIs - enough to evaluate paid-tier models seriously.
  • Cursor's Hobby plan for a permanent editor - the strongest no-expiration free tier.
  • Cline if you would rather keep your editor and drop in free open-weight models.
  • Devin's free plan for teams evaluating agents before committing budget.

Shopping for organization-wide seats? The startup hub owns those programs instead.

Rows marked Verified were tested by a person, not scraped. Listed rows are live offers still waiting on their first check.

  • We sign up and claim the credit or plan with a fresh account, then run real coding tasks against it.
  • We record what is actually free: usage caps, model lists, and whether a card is demanded.
  • We re-check monthly. Entries are re-dated when something changes; offers that turn dark or bait-and-switch are pulled and, if dishonest by design, named on our scam list.

Frequently asked questions

What is aifree.dev?

aifree.dev helps everyone access AI through a curated directory of free AI tools, API credits, free tiers, and startup programs for coding, image, voice, video, and students - verified regularly.

How are offers presented?

Each offer includes its access details, free models when available, and expiration information when provided. Limited-time deals stay visible so they are easy to compare.

Do education and startup programs need verification?

Yes. Providers usually ask students to verify their status with a school email, student ID, or a program like the GitHub Student Pack, and ask startups to verify company details such as age, funding, or website. Check each offer’s claim page for the exact requirements.

What kinds of free AI offers are listed?

Free tiers and free trials from AI providers, free API credits, startup and student programs, and free tools for coding, image generation, voice, and video.

How can I suggest a tool or report a broken link?

Use the submit form: paste the offer page URL and a short note. A person checks every submission before anything is listed. Broken links and changed terms go through the same form.
