How to enter

Choose a challenge. Run a sample. Submit your work.

Pick a problem, use the starter template or ask an AI coding assistant to help you adapt it, run the sample locally, then send us the link. The challenge page tells you exactly what is measured; the brief gives you the shortest path in.

1

Choose a problem

Read the plain-language brief and decide whether the task is a good fit for you.

2

Run one sample

Start from the template, change one thing, and check that your agent produces the required output.

3

Send the link

Follow that challenge’s submission instructions. Send the required files and exact code version to submit@builderr.ai.

Choose a challenge

Start with the short brief.

Try a small exercise

Catch a wrong answer in a company-research agent.

Two fictional companies have the same name. Fix the Python example so it keeps their facts separate, saves supporting sources and handles a failed update without inventing a change.

Runs offline with Python 3.9 or newer. No API key, paid service or signup needed. Includes instructions, a worked solution and tests. This is practice, not a competition entry.

Download the Python exercise ↓

Unzip it, open README.md and run the example. For the full task and scoring, read the Signalpost challenge →

Stay in the loop

Get challenges that fit your skills.

Tell us what you like building. We’ll email you relevant challenges with the task, prizes and rules, so you can decide whether to enter.

Send your preferred topics and, if you have one, a project or demo you worked on. Include “Yes, send me relevant challenge updates” if you want to hear from us. We only add you after receiving your permission. You can stop by replying “Stop”.

No email app? Write to inquiries@builderr.ai with your topics and permission.

This is optional and does not enter you into a competition. We keep your message and contact details private; we won’t publish a profile without your permission. You can browse challenges and use starters without joining.

Copy the email template

May Builderr email you relevant challenge updates? Write Yes or No:

I understand this email does not enter a competition or create a public profile.
I can stop updates by replying Stop. Please keep my contact details and this message private.

Please use public or redacted examples. Do not send passwords, API keys or private client data.

What the technical pages are for

The brief is the friendly starting point, not a replacement for the rules. Each challenge page contains the full input format, scoring weights, limits, sample questions, model policy, and what happens to your submission. Read those details before you submit.

You can use an AI assistant, a starter repo, or a collaborator. You still own the work and are responsible for checking that it runs, follows the rules, and does not include private keys.
