AI Agent Playground
Design, build and test AI (prompts, context, tools and agents) through structured experiments... not one-shot guesswork.
- Detailed agent execution tracing and testing
- Node-based prompt composition
- Reusable prompt components
- Variant testing and comparison
- Version history for prompt evolution
Built for Iterative Context Engineering, Not One-Shot Generation
Most tools treat prompts as throwaway text you generate once and move on. But real AI work is iterative: you adjust structure, constraints, and context until the output is actually right.
ProForge gives you a visual canvas where prompts are composed as connected nodes, so you can refine specific parts, run structured experiments, and build on what works instead of starting over every time.
- Compose prompts from reusable nodes like
{output},{audience},{action},{examples}, and{style} - Run A/B variants and compare outputs side-by-side
- Keep a version history so you never lose what worked
How ProForge Works
- 1Compose nodes: build your prompt from reusable, editable blocks on a visual canvas
- 2Run variants: send prompt outputs into agent chat or image generation pipelines and compare results
- 3Keep winners, iterate:version the prompts that work and continue refining from a solid baseline
Everything You Need for Iterative Prompt Engineering
Detailed Agent Execution Logging
See what is really happening during agent execution.
Reusable prompt components
Build once, reuse everywhere.
Prompt history + versioning
Iterate without losing what worked.
A/B variants
Compare approaches and pick winners faster.
Prompt testing / evaluation
Reduce guesswork with structured tests.
Templates library
Start from proven structures for common tasks.
Prompt optimizer / rewriter
Rewrite for clarity, constraints, and better results.
Build your “best AI prompts” by testing instead of guessing.
Agent and Image Prompt Workflows
ProForge is built for iterative workflows, feed prompt outputs into agent chat sessions or image generation services, compare variants, and refine over time.
Image Prompt Generator
Available NowCreate and iterate on image prompts for Nano Banana, Seedream, and GPT Image using reusable components for subject, style, composition, and constraints.
- Consistent style with saved blocks
- Faster iteration by editing only what changed
- Better outputs through variants and tests
Agent System Prompt Generator
Coming SoonBuild agent system prompts that define behavior, rules, and constraints. Then test them against ChatGPT, Claude, and Seed before deploying in your workflows.
- Mock tool calls to validate agent behavior
- Versioned prompts for reliable agents
- Designed for workflows like Relevance AI, Gumloop, and n8n
Video Prompt Generator
Coming SoonGenerate structured video prompts for Seedance, Veo, and Sora. Ideal for small teams building an AI image to video generator workflow with consistent scenes, camera motion, and pacing.
- Reusable scene blocks (camera, motion, transitions)
- Storyboard-ready prompts from a single canvas
- Coming soon, join the waitlist to get access first

Iterative Prompt Engineering FAQ
What is ProForge and how does it differ from other prompt tools?
ProForge is a visual node-based prompt canvas built for iterative prompt engineering. Instead of one-shot generation, it lets you compose prompts as reusable nodes, run structured variants, and improve outputs over time through experimentation.
What workflows does ProForge support?
ProForge works across agent chat workflows and image generation pipelines. You can feed prompt outputs into agent sessions or image services, compare variants, and iterate based on real results. Video support is coming soon.
Who is ProForge best suited for?
ProForge is ideal for teams and individual builders who iterate on prompts over time, running experiments, comparing variants, and maintaining a version history. It is not designed for one-shot prompt generation with no experimentation loop.
Can I version and compare prompt variants?
Yes. ProForge includes version history for prompt evolution and A/B variant testing so you can compare outputs side-by-side and keep the winning approach.
Does ProForge support image generation workflows?
Yes. You can use ProForge to build and iterate on image prompts for services like Nano Banana, Seedream, and GPT Image using reusable node-based components.
When will early access be available?
