Hi, I'm using Archestra with OpenRouter's Free Models Router as mentioned in the webinar. Simple chat works, but when I ask it to generate an application, I get errors like empty response without content or tool calls or incomplete_tool_call. Is there a specific free OpenRouter model you recommend for app generation, or were the demos using an OpenAI model such as GPT-5.x?

Hi! I’m getting ready to submit my Apps Hackathon project and wanted to clarify the video requirements.

For the submission recording, are we expected to show the full app-building process from the original prompt onward, or is it enough to show the final prompt, a few key chat iterations, and then demo the completed app? Do judges need to see the chat logs or exact prompts used?

Is there a recommended video length or maximum duration? Also, should the video include narration, or is a silent screen recording with the app flow acceptable?

A few other questions:

• Should the recording focus mostly on the final app experience, or also explain how the MCP server and live data integration work?

• Do we need to show the submission PR creation process in the recording?

• Are there any specific items that must be visible, such as the MCP servers used, the live-data state, or the generated app prompt?

• How heavily is UI/UX and visual polish weighted compared with technical complexity, usefulness, and depth of MCP integration?

Thank you! I just want to make sure I record and submit everything correctly.

Hi team , i want to add google maps to my app but that mch is not available in the catlog any idea how to add that?

👋 Hi everyone!

Hey all Hackathon App builders 👋

To help you get your submission ready, we’ve added a short video guide on how to record and submit your app - check it out here.

Hey

I wanted to know is it necessary to record the session of prompts and chat with my LLM or just at the end I record the result nad just keep it short and so on like is it a factor considered in judging or the final github thing will be the one judged only

pls lmk so I don't miss the thing out for not recording ._.

Hi

Running Archestra in a GitHub Codespace. Whenever the Codespace

restarts (idle timeout, etc.), the public 3000 URL 404s, even though

the app is healthy internally (curl to localhost:3000 works fine,

container shows healthy). Port re-forwarding and full Codespace

restarts don't fix it — only deleting and recreating the Codespace

does, which is a pain since I lose my GitHub OAuth setup each time.

Anyone seen this / know a fix?

Hey can I make my community post right now? it's asking for my gallery link.

hey ... wanted to know if I'm the only one facing this issue ... when working on my apps and recording the session the record mid session auto stops like and not save just it stops and resets to 00:00 like idk what's going on but I have been into workign on my stuff and thinking that the thing is recording but nothing was recorded like wow and why is that ... is it an issue in the sys or my side or what's going on exactly anybody faced smth similar ??

It show this when I upload too video and I try several time like 10 to 12 times.

This recording has no description or build prompt yet — add them from the player before sharing.

So I go for manually.. Is this right?

Hi all, apologies if it wasn't clear before 🙏 Recordings that include building steps would receive a higher evaluation than recordings of the final apps only.
