Best for

Developers and power users who want a chat client that can extend itself on demand, and hobbyists who enjoy prototyping small widgets or themes through conversation.

Skip if

Teams that need transparent model choice, a documented API, predictable enterprise pricing, or generated code that runs outside the vendor's chat runtime.

Foomchat is a conversational AI application that turns natural-language requests into installable, live-generated features inside the chat surface itself. Instead of the model producing only text or file output, users describe a tool they want — a pomodoro timer, a theme, a custom widget, a layout tweak, a small utility — and an agent writes the code, spins the feature up in place, and offers to install it into the workspace. Once installed, features can be edited, kept, rolled back, or shared to a curated community marketplace where other users can browse and one-click install submissions that have been approved. In effect the chat window becomes the runtime for an ever-growing catalogue of small apps that the user (or the community) generated on demand. The intended audience is developers and tinkerers who want a self-modifying chat client, plus non-developers who like the idea of asking for a UI element and getting it without touching code. Common workflows include prototyping a small productivity widget in a single conversation, forking or restyling a community-submitted theme, iterating on a personal dashboard component through repeated turns with the agent, and publishing polished features to the marketplace for others to install. The version-control layer around each generated feature is what pulls the experience closer to an agent framework than a chatbot: the user is directing a loop that produces persistent artifacts, not just messages. Foomchat is early-stage: the site does not disclose which underlying model powers generation, whether an API exists, or the shape of paid tiers beyond the free-credit onboarding.

Editor's take

The pitch — a chat app that grows new features by asking for them, with version control and a marketplace — is a genuinely interesting spin on agentic UX. But with no disclosed model, no API, and no visible pricing beyond free credits, this is a curiosity to try, not a tool to standardise on. Worth ten minutes if the concept intrigues you.

Pros

✅ Generates installable in-app features from chat rather than dumping code for the user to wire up themselves
✅ Version control on every generated feature — edit, keep, or roll back without leaving the conversation
✅ Community marketplace lets users browse and install features other people have built and submitted
✅ One-click install for themes, widgets, and layouts lowers the barrier for non-developers
✅ Free credits with no card required makes it painless to evaluate
✅ Positions the chat window itself as the runtime, which is a genuinely different take on agent UX

Cons

⚠️ The underlying model family is not disclosed, so buyers cannot assess capability or data-handling implications
⚠️ No public pricing beyond free credits — hard to plan around long-term cost
⚠️ No documented API, so features live inside Foomchat's own client rather than composing with other tools
⚠️ Marketplace quality depends on curation velocity; early catalogues are often thin
⚠️ Generated features are scoped to the chat surface, not standalone apps you can host elsewhere
⚠️ Very new product with limited third-party reviews or track record to reference
