One glance tells you whether to keep going or step in. Pick a state to see it.

Small creature. Careful design.

Your code stays on your computer, and only real work counts.

  1. Pets

    One of your own, plus one for each provider. Your primary Flaskling belongs to no model company. Each provider you use hatches its own pet, which grows only with that provider’s time.

    Flaskling, your primary
    • Ignis Fire, for Anthropic
    • Aqua Water, for OpenAI
    • Terra Earth, for Google

  2. Growth

    Grows with real working time. Idle sessions, approval waits and gaps over five minutes don’t count. Up to 6 credited hours a day: 4 from working time, 2 more from token use.

  3. Privacy

    It never stores your code. Of what it records, only daily totals, a subscription hash and live status leave ~/.flaskling, for your account.

    Agent events, model names and token counts, hashed session IDs, commit counts

    Prompts, code, tool input or output

  4. Setup

    Nothing changes unless you say so.

    • Session-scoped hooks; without flaskling setup or auto-wrap, your settings files stay untouched
    • flaskling setup asks before it adds the agents’ plugins and login items
    • Every key passes through except ctrl ] (menu) and Shift PgUp (scroll)
    • Header can be full, compact or hidden

  5. Desktop

    Out onto your desktop. Coming soon. Walking the floor, crossing monitors, sitting on windows, napping. Pick them up and toss them.

Questions, answered.

More in Customer Support, or write to us there.

Do I need an account?
Yes. You need an account to use Flasklings, and your pets, growth, essence and items belong to it. Sign up on the dashboard with GitHub or Google, then connect the CLI with flaskling login and run flaskling setup: it installs the collector that records your work for your account. This works on macOS, and on Linux as a preview. Windows isn’t supported yet.
Why isn’t my Flaskling growing?
It grows only with credited working hours. Idle sessions, approval waits and gaps over five minutes don’t count, and a day credits at most 6 hours: 4 from working time and 2 more from token use.
Do items make my pet stronger?
No. Everything in the store is looks only: nothing you buy changes growth, rankings or arena power.
