Hey Product Hunt!
I built PromptForge because I was tired of the endless trial-and-error cycle of prompt engineering. As someone who works with AI daily, I found myself constantly tweaking prompts, losing track of what worked, and having no systematic way to evaluate improvements.
The problem: Most prompt tools are just fancy text editors. You write, you test, you hope for the best. But there's no real engineering discipline.
What makes PromptForge different:
Systematic evaluation - Generate comprehensive test suites automatically
Built-in analytics - Track what actually works across different scenarios
Variable testing - Test edge cases, robustness, and consistency
Prompt library - Never lose a working prompt again
Dual analysis - AI-powered feedback on your prompts before you even test them
Why I built it: I wanted to bring the same rigor to prompt engineering that we have in software engineering - version control, testing, systematic improvement.
Currently supporting Claude, GPT-4, and Azure OpenAI with more providers coming soon. Docker deployment makes it dead simple to get started.
What would you want to see in a prompt engineering tool? Always looking for feedback from fellow AI builders!
Prompt Forge is a practical tool for AI developers focused on prompt engineering. It offers a structured way to craft, test, and evaluate prompts with analysis features—ideal for refining interactions with LLMs and improving output quality.
Congrats on the launch!
Interesting new AI tool to try. We're also developing AI ecommerce apps and utilizing prompting to create many key outputs daily. And yes, prompt engineering isn't merely about attempting to write perfect sentences with correct grammar; it's a fundamental skill across industries.
I found a similar product that is already in open beta testing, its name is GenumLab, they position themselves as a PromptFinOps platform. What's the difference? They also have multi-vendor support, audit capability, Canvas Chat. They also have full control over the prompt, its stability can be tested with test cases. I also noticed that you and them have AI Assertion. What are you better at and how can you compete with them?
Looks like a solid tool for refining AI prompts! The systematic testing and analysis features should definitely save time and help in dialing in the perfect prompts. Excited to see how it evolves, especially for streamlining workflows across different models
The auto - generated test suites and dual analysis in PromptForge are total game - changers, bringing real engineering discipline to prompt crafting! For folks doing complex multi - step prompt chaining, how does PromptForge help manage and evaluate the interplay between different prompt segments to ensure cohesive results?
This product really highlights in the built-in analytics and ability to automatically generate test suites. It’s inspiring to bring real software engineering principles to AI prompts.
I can see the future where every second person tomorrow will be the prompt engineer. So product like promptforge is the need for today .
I would be love to try and be a user for promptforge ❤️
Congrats on the launch, Manav & team! 🚀 PromptForge 2 is looking to be a game-changer for serious prompt engineers. I especially love the test suites, versioning, and analytics. The built-in prompt feedback and edge-case testing really set it apart from basic editors.
Excited to see future updates like local model support (Ollama/LM Studio) and more LLM backends. Would also love to see collaboration features soon. This feels like the VS Code for prompt development.
Well done and wishing you continued success! 👏🔥
Huge congrats on the launch! 🎉
Just upvoted - this will definitely come in handy for our team's current project. Hoping to launch something soon as well, so I might be back here looking for support 😊 Keep building!
Congrats on launch! Brilliant solution to end prompt engineering trial-and-error chaos with systematic testing and analytics.
Congrats on the launch! Quick question. Does PromptForge support comparing performance between different prompt versions? Really looking forward to trying it out!
This is a super cool product! I can definitely relate to the pain point of having to prompt endlessly.
This looks like a powerful tool for anyone working with AI prompts. The ability to craft, test, and evaluate prompts in a structured way—with built-in analysis tools—is incredibly valuable for improving accuracy and consistency. Great work on making prompt engineering more accessible and systematic! visit more
This is super useful. Congrats on shipping this and making it open source. 🙌🏻🚀
This is cool — would love to be able to run it locally and use @LM Studio or @Ollama for inference. Would that be possible? (I also have Docker installed but it'd be nice to avoid unnecessary $$ cloud bills)
