Challenges & events

Public challenge pages for builders who want to ship real projects, not just attend. Start from a Build Packet, submit repo/demo evidence, and turn approved work into proof for the developer, product team, and tool profile.

Plan a build sessionPublish a build
Live build sessionsNo hosted runtime
From public brief to proof ledger.

Run a timed product build without taking on compute cost: publish the session page, hand builders a Build Packet, collect published projects with repo/demo proof, and show approved proof or standings when useful.

  1. 01

    Public session brief

    A public challenge page defines the product, build goal, schedule, requirements, credits, and judging context.

  2. 02

    Build Packet

    Builders start from stack guidance, agent handoff notes, docs, risk boundaries, and useful partner offers.

  3. 03

    Repo/demo submission

    Each builder submits a repository, demo link, and build notes instead of a badge scan or attendance-only metric.

  4. 04

session.log

$ tokensand session publish

> public brief ready

> build_packet scoped

$ builder submit repo demo notes

> proof ledger pending review

> standings optional

This creates a live-event path with owned pages and proof workflows. Builders keep using their current IDE, repo, and agents.

Enterprise proof path

Live build submissions create attributable project proof.

Connect first-party product events to verify usage and retention after the build is published.

Free company workspaces require a work email. There is no pricing or self-checkout; paid enterprise access is provisioned manually after a sales call and agreement.

Proof ledger

Approved work becomes reviewable adoption evidence for the builder profile, tool page, and company workspace.

  • 05

    Optional standings

    Rankings stay optional and only sit on top of approved proof, useful participation, and completed projects.

    • No hosted container runtime required.

    Builders use their own repo, local setup, or coding agent.

    tokens& owns the brief, packet, submission, proof, and standings layer.
