When Custom GPT is better
Custom GPT is the clearer choice when your audience already works in ChatGPT and your goal is to shape a GPT experience there. Staying in that familiar product can matter more than publishing a separate Skill-based web app.
Custom GPTs and Skill2Web start from different jobs. A Custom GPT tailors an experience inside ChatGPT; Skill2Web turns a compatible public GitHub Skill into a focused web app whose source-grounded answers let users inspect the supporting material.
Quick verdict: Choose Custom GPT if you want a tailored GPT experience inside ChatGPT. Choose Skill2Web if you want to convert a public GitHub Skill into a shareable, source-grounded web app.
The useful question is not which product wins in general, but which starting point and user experience match your work.
| Compare | Custom GPT | Skill2Web |
|---|---|---|
| Best fit | A tailored GPT experience used inside ChatGPT | A focused web app built from an Agent Skill |
| Starting point | A GPT configured for a specific purpose | A compatible Skill in a public GitHub repository |
| Answer context | The GPT experience you configure | Source-grounded answers with supporting material users can inspect |
| Conversion | Not a Skill-to-web conversion workflow | Three free checks per day, then 500 credits to convert |
| Visibility | Used through ChatGPT | Private by default, or reviewed before a public listing |
| Model keys | Part of the ChatGPT experience | Members can connect OpenAI, Claude, or Moonshot; BYOK chats use no platform credits |
Custom GPT is the clearer choice when your audience already works in ChatGPT and your goal is to shape a GPT experience there. Staying in that familiar product can matter more than publishing a separate Skill-based web app.
Skill2Web fits when your source of truth is a public GitHub repository containing a compatible Skill, you want source-grounded answers with inspectable supporting material, and you want a private app or a reviewed public listing.
Provide the repository that contains the compatible Agent Skill you want to convert.
You can check compatibility up to three times per day before spending credits.
After a compatible check, choose to use 500 platform credits for the conversion.
The result is private by default. A public listing requires review, and creators receive 20% of credits spent on their public Skill.
No. Custom GPTs are a strong fit for tailored experiences inside ChatGPT. Skill2Web is designed for converting compatible public GitHub Skills into source-grounded web apps.
Answers are grounded in the Skill's source material, and users can inspect the sources supporting an answer.
No. The conversion flow starts with a public GitHub repository.
You can run up to three free compatibility checks per day. A confirmed conversion uses 500 platform credits.
Members can connect an OpenAI, Claude, or Moonshot API key in Settings. Chats using that key consume no platform credits.
No. It is private by default. A public listing goes live only after review.
Check a compatible public GitHub repository, or explore existing source-grounded Skills before you decide.
