Summary
Nick Saraev reviews Freebuff, a new platform that provides access to frontier AI coding agents — including GPT 5.6 Luna, DeepSeek V4.1 Flash, and GLM 5.3 Flash — at zero cost by replacing subscription fees with in-session advertisements. Saraev positions it as an alternative to paid tools like OpenCode ($120/year) or Codex ($240/year), and notes that GLM 5.3 Flash scores 45 on the intelligence benchmark he references, compared to Claude Fable 5.1’s 53 and GPT 6 Astra’s 53 — competitive enough for many coding tasks.
The walkthrough covers the full signup flow (no credit card required), the “free bucks” daily allowance system that resets at midnight Pacific, and the browser-based IDE interface, which includes diff views, a terminal, plan and build modes, and multi-tab support. Saraev runs two simultaneous sessions — one building a personal portfolio site using Luna, another generating a stick-figure walking game with GLM 5.3 Flash — to show how the models and UX differ across tiers.
The video is candid about rough edges: one session ran slow, his machine ran hot, and he hit confusion around multi-tab limits before discovering they were supported. Saraev explicitly disclaims any affiliation with Freebuff, framing the review as genuine enthusiasm for a model that lowers the access barrier for developers in regions or financial situations where recurring AI subscriptions aren’t practical.
