Developer spends $2,000 in tokens to vibecode a free Photoshop alternative with GPT-6 Astra
A developer vibecoded a free Photoshop alternative with GPT-6 Astra, reaching 170 users on day one, and shares a research-then-plan-then-code process, a single agent with one growing context, and prompt caching to save money.
One developer spent $2,000 in tokens and vibecoded a free Photoshop alternative built with GPT-6 Astra 170 users on day one. His process works for vibe coding pretty much anything: Research first, plan second, code third. He mapped every Photoshop feature before Astra wrote a line, so the plan came from facts instead of guesses. One agent, one context, growing over time. No crew of specialists. Split into separate agents only once your prompt gets too branchy. And on the money, since $2,000 goes fast: cache your system prompt and tools, input is $10 per million tokens, cached is $1. Stay under 272K input per request too, past that the whole thing bills at double.
