TurnKeeper answers the oldest question in team Slack channels: whose turn is it? It runs recurring rotations — support triage, standup facilitation, code review duty, on-call handoffs — and announces the current person on your schedule. Skips, swaps and vacations are handled with fairness accounting, and every assignment can be explained with one click from an append-only audit trail. No AI in the decision path. Flat pricing: €19/month per workspace, unlimited users, 30-day free trial without a credit card. EU-hosted (Germany).

Possible disadvantages of CodeSandbox

    Some users experience lag and slower performance, particularly with larger projects, compared to local development environments.
  • Limited Customization
    While convenient, the pre-configured environments might limit advanced customization options available in local IDEs.
  • Dependency on Internet
    As an online platform, a stable internet connection is required to use CodeSandbox effectively, which could be a limitation in areas with poor connectivity.
  • Free Tier Limitations
    The free version comes with certain restrictions on resources and functionality, which might not be sufficient for larger or more complex projects.
  • Security Concerns
    Storing code in an online platform can raise security concerns, especially for sensitive or proprietary projects.
  • Learning Curve
    Despite its ease of use, developers new to online IDEs might face a learning curve in adapting from traditional, local development environments.

Questions & Answers

As answered by people managing CodeSandbox and TurnKeeper.

Which are the primary technologies used for building your product?

TurnKeeper's answer:

TypeScript (Bolt.js for Slack), PostgreSQL with an append-only event ledger as the source of truth, Docker, hosted on EU infrastructure (Hetzner, Germany) behind Cloudflare. Payments via Paddle as merchant of record.

What makes your product unique?

TurnKeeper's answer:

Every assignment is explainable. TurnKeeper keeps an append-only ledger of all assignments, skips, swaps and absences, so it can always answer "why is it my turn?" — skipped turns transfer fairness credit instead of silently piling up on whoever is next. And there is deliberately no AI in the decision path: a tool that decides whose turn it is should be deterministic and auditable, not probabilistic.

How would you describe the primary audience of your product?

TurnKeeper's answer:

Software and support teams of roughly 4–50 people who rotate recurring duties through Slack: support triage, standup facilitation, code review duty, on-call handoffs. Typically teams that have outgrown the pinned spreadsheet or /remind hack but don't want a full incident-management platform for duties that aren't incidents.

Why should a person choose your product over its competitors?

TurnKeeper's answer:

Three reasons: transparent fairness (an audit trail instead of a black box), honest vacation handling (absences are skipped visibly, with the reason shown in the announcement), and flat pricing — €19/month per Slack workspace with unlimited users, versus the per-user pricing most alternatives charge, which punishes growing teams. It's also EU-hosted (Germany) with minimal Slack permissions: it cannot read your messages.

What's the story behind your product?

TurnKeeper's answer:

Built by a solo founder after seeing the same pattern at every company: rotations managed via outdated spreadsheets, reminders that ping people on vacation, and homegrown bots that die when their author changes teams. Slack's Workflow Builder still can't do rotations (no persistent state, no "next person" step), so TurnKeeper fills that gap with boring, reliable, auditable software.

  • Thankful for CodeSandbox
    I am thankful for a platform like CodeSandbox because it allows me to offload majority of the processing power and memory resources to the cloud. With a local VS Code installed, I can tunnel in via a remote connection to work on my projects, tinker, or do a deep-dive on certain topics; all while ensuring that the RPi 4 still has sufficient resources left to run other things in the background. - Source: dev.to / over 1 year ago
