As answered by people managing JSFiddle and AskCanvas.
AskCanvas's answer:
AskCanvas transforms feedback into visible, community-driven conversations instead of static survey responses.
Unlike traditional feedback tools where users submit ideas and never hear back, AskCanvas enables transparent discussions, reactions, and participation between users and product teams.
It combines feedback collection, collaboration, and public interaction in one platform — helping users feel heard while giving teams richer insights and stronger engagement.
AskCanvas's answer:
AskCanvas is built for engagement, transparency, and participation — not just data collection.
Traditional feedback and survey tools often feel one-sided: users submit responses and never see what happens next. AskCanvas changes that by turning feedback into visible conversations where users can discuss ideas, react, collaborate, and stay involved.
Key reasons to choose AskCanvas:
Public and transparent feedback discussions Community-driven participation instead of isolated responses More engaging than static surveys and forms Helps users feel heard and connected Encourages ongoing conversations between teams and users Combines feedback, collaboration, and interaction in one platform
AskCanvas is ideal for startups, SaaS products, and communities that want stronger user engagement and more meaningful product feedback.
AskCanvas's answer:
AskCanvas is built using modern web technologies focused on scalability, real-time interaction, and user experience.
Primary technologies include:
React.js for the frontend user interface Node.js for backend services and APIs MongoDB/PostgreSQL for data management Real-time communication technologies for interactive discussions and updates AI-powered features for smarter feedback analysis and engagement workflows
The platform is designed to support collaborative discussions, transparent feedback systems, and scalable SaaS infrastructure for growing communities and product teams.
AskCanvas's answer:
AskCanvas is designed for startups, SaaS companies, indie hackers, product teams, and online communities that want more engaging and transparent ways to collect user feedback.
It is especially useful for teams that:
Build products with active user communities Want users to participate in discussions instead of submitting isolated feedback Need a public or collaborative feedback system Care about transparency and stronger customer relationships Want to turn feature requests and feedback into ongoing conversations
The platform is ideal for founders, product managers, developers, and community-driven businesses looking to improve user engagement and product decision-making.
AskCanvas's answer:
We noticed that most feedback tools treat users like data sources rather than participants. People fill out surveys, submit feature requests, or leave feedback — but rarely feel heard or involved afterward.
AskCanvas was created to change that experience.
Instead of collecting isolated responses in private dashboards, AskCanvas turns feedback into visible conversations where users can discuss ideas, react, collaborate, and stay connected with product teams transparently.
The goal behind AskCanvas is simple: make feedback feel more human, interactive, and community-driven — helping teams build stronger relationships with their users while gathering richer insights.
AskCanvas's answer:
AskCanvas is currently focused on early-stage adoption and is being actively tested by startups, indie hackers, SaaS founders, and product-focused communities.
The platform is gaining interest from teams looking for a more transparent and community-driven alternative to traditional feedback and survey tools.
While AskCanvas is still in its early growth stage, the focus is on building strong engagement with startup teams, product builders, and online communities before expanding to larger enterprise customers.

Test your javascript, CSS, HTML or coffeescript online with jsfiddle code editor. Jsfiddle – code playground.
JSFiddle cannot be used to host code on your server. The code has to be on JSFiddle and is public all the time.
What is missing from JSFiddle is live previews. You have to basically refresh the page by clicking on the play button. And compared to other playgrounds, JSFiddle is probably the slowest. Another slightly frustrating...
