Show HN: I built a social media management tool in 3 weeks with Claude and Codex

A developer on Hacker News announced that they had built a full‑featured social‑media management platform in just three weeks, using Anthropic’s Claude for natural‑language tasks and OpenAI’s Codex CLI for code generation. The “Show HN” post details a web app that lets users link multiple accounts, schedule posts, generate copy with AI, and view real‑time engagement analytics—all assembled from prompts fed to Claude and snippets auto‑written by Codex. The creator says the prototype is already handling a handful of beta users and plans to roll out a paid tier within weeks.
The rapid turnaround matters because it showcases how today’s large language models can replace large development teams for niche SaaS products. Claude’s ability to draft marketing copy, suggest hashtags and even flag potentially risky language cuts the need for separate copy‑writing resources, while Codex’s code‑completion speeds integration with APIs from Twitter, LinkedIn and Instagram. If the tool gains traction, it could pressure established players such as Buffer, Sprout Social and university‑focused platforms that rely on manual engineering cycles to add features.
What to watch next is whether the project can scale beyond a prototype. Key indicators will be user growth, churn rates and the developer’s decision to open‑source parts of the stack or seek venture funding. Anthropic’s recent push to make Claude more developer‑friendly and OpenAI’s ongoing refinements to Codex suggest a fertile ecosystem for similar “AI‑first” tools. The next few months should reveal whether LLM‑driven development can consistently deliver production‑grade SaaS at startup speed, or if hidden complexities in security, compliance and platform API changes will temper the hype.
