AI prompt playground template for SaaS
Interactive AI prompt playground template for SaaS. A prompt testing environment with a left panel for the system prompt, user prompt, and parameter sliders for temperature, max tokens, and top p with live token counters, and a right output area showing two model responses with latency, token count, and cost per run for each. Tab modes for comparing two models, a single model, or a batch of prompts. Paste it into Claude Code, Replit, Lovable, ChatGPT Codex, Bolt, or Cursor.
About this vibe coding template
Interactive AI prompt playground template for SaaS platforms and developer tools. A prompt testing environment for comparing model outputs and iterating on prompts before deploying them in production. The page layout splits the screen: a fixed left panel for configuration and a scrollable right panel for output. The configuration panel has three editable areas: a system prompt textarea with a live token counter, a user prompt textarea with its own token counter, and a parameter section with labeled sliders for temperature, max tokens, and top p, each with a numeric input alongside the slider track. An estimated cost section at the bottom of the configuration panel shows the projected cost for the current prompt and parameter combination across both selected models. The right panel has a tab bar for switching between compare mode, single model mode, and batch mode. In compare mode, the right panel shows two output panes side by side. Each pane has the model name and provider label in the header, a rerun button, a scrollable response area with inline code support, and a footer row showing latency in milliseconds, token count, and cost for that individual run. The playground does not call a model on its own; connect the run action to your model API and replace the parameter sliders with the parameters your models accept. Paste it into Claude Code, Replit, Lovable, ChatGPT Codex, Bolt, or Cursor.
Build an entire website with this template
A website is a handful of pages that need to feel like one place, so a single well built section can set the style for every page after it. Copy the template, paste it into Claude Code, Replit, Lovable, ChatGPT Codex, Bolt, or Cursor, and send this alongside it.

Use the HTML I am pasting below as the design system for my entire website. Match its type scale, spacing, colors, border radius, and component styling on every screen you build from here. Reuse its buttons, cards, and layout rhythm, and keep anything new in the same visual language. When I ask for a screen you have not seen yet, infer the design from these patterns and keep it consistent with what is already there. Start with the home page, then wait for me to name the next one.
Common questions about this template
What does this AI prompt playground template include?
A system prompt textarea with a live token counter, a user prompt textarea with a token counter, temperature, max tokens, and top p parameter sliders with numeric inputs, an estimated cost line, a tab bar for compare, single, and batch modes, and two output panes in compare mode showing model name, response body with inline code, and a per run latency, token count, and cost footer.
How do the parameter sliders work?
Each parameter has a labeled section with a numeric input on the right and a slider track below. Moving the slider updates the numeric input and vice versa. The estimated cost section updates to reflect the new combination. Replace the parameter names and ranges with the parameters your own models accept.
How do the output panes compare two models?
Each pane shows the model name with a provider label in the header. The response scrolls independently. The footer shows latency in milliseconds, token count, and cost for that specific run. The two panes sit side by side so the responses can be read in parallel at the same scroll position.
What does the estimated cost section show?
The estimated cost section shows the projected cost for one run across both models with the current prompt and parameter settings. Replace the cost calculation with your own pricing model and model rates.
Which tools work with this AI prompt playground template?
Claude Code, Replit, Lovable, ChatGPT Codex, Bolt, and Cursor. Paste it in, connect the run button to your model API, replace the parameter sliders with your own parameters, and update the model names and pricing.
How do I build an entire website with this template?
Yes, and that is the fastest way to use it. Hand this template to Claude Code, Replit, Lovable, ChatGPT Codex, Bolt, or Cursor as your reference design, and ask for the rest of the website one screen at a time.
