PromptStack
Smarter prompts. Seamless workflows.
Everything you need to build AI workflows, nothing you don’t
Prompt Chaining
Chain prompts to flow outputs directly into the next step - no copy-pasta required.
Organized
Keep everything tidy with a folder-based structure. Organize workflows by project, client, or idea so nothing gets lost.
BYOK
(Bring Your Own Key)
Use your own OpenAI, Anthropic, or Gemini keys together in the same workflow. Your data stays yours.
Built for Flow
A clean interface designed for fast iteration, branching ideas, and focused building — without getting in your way.
Built for Builders
Designed for indie devs, creators, and curious tinkerers. Built to stay out of your way.
Built for Iteration
Save workflows once, clone them as needed, and tweak prompts to instantly test new ideas across projects or use cases.
Built by a developer, for people who want their tools to respect their time, because we all have more important things to do.
PromptStack wasn’t built to chase the AI trend, it was built to solve a personal pain.I’m Joshua Allen - indie developer, software engineer, husband, and dad to a curious 3-year-old. I juggle code, creativity, and family life every day, and I don’t have time for tools that fight back.When working with LLMs, I kept hitting the same walls:
Prompt inputs were unwieldy
There was no clean way to branch or evolve ideas
I couldn’t track experiments without duct-taping tools together
I didn’t want a bloated dashboard, I wanted a workbench. Something lightweight. A tool that respects both your time and your curiosity. Something you could grow with, from quick tests to production workflows, without needing an expensive subscription or team license.PromptStack is my answer to that.If you’re a builder, a tinkerer, or someone trying to stay curious without burning out - this is for you.
