Freebuff Free Coding Agent (ad-sponsored, 100 Freebucks per day)

Desktop / CLI / Web coding agent that is completely free, sponsored by text ads: 100 Freebucks every day to spread across multiple models; putting the whole day's allowance on a single model gives roughly 6 hours of DeepSeek V4.1 Flash, 6 hours of GLM 5.3 Flash, or 10 hours of MiMo 2.6 Flash; no API key or credit card required

Verbatim from the official site: "100 Freebucks every day. Spend them on any mix of these models. No subscription required." "Hour totals use your whole daily allowance on one model; they aren't added together. Daily Freebucks refill at midnight Pacific and don't carry over. Access depends on your country and VPN. Session usage limits apply." The page's "Free hours per day, by model" chart gives the daily hours per model (checked against the position of the page elements): Space Bunny Alpha unlimited, Solar Mini 4 at 20 hours, MiMo 2.6 Flash and Solar Pro 4 at 10 hours each, GLM 5.3 Flash and DeepSeek V4.1 Flash at 6 hours each, GPT-6 Luna at 5 hours, MiMo 2.6 Pro at 3 hours. Gemini 3.8 Flash and Muse Spark 1.3 require a paid plan; GPT-6.1 Sol is free only in the US, one session per account per day. The official FAQ says the reason it is free is "supported by text ads".

⚠️Available models and daily hours are adjusted with the official operations (the official tweets have launched new free models several times since 2026-08). The official page says availability depends on your country and VPN, but the collapsed FAQ content listing exactly which countries are supported could not be read, so users in mainland China should test first. Login methods were not checked one by one (the page has a Sign in entry). The product comes in three forms: Desktop (macOS / Windows / Linux), a CLI installed globally via npm, and a Web site builder, and the official page says No API key, no credit card.
