Is Observer free to start?

Yes. Free includes 1 status page, 1 agent and 5 subscribers, with no card required.

Do you charge per seat?

No. Each plan is one flat monthly price, with no per-seat fees.

Do alert destinations need a paid plan?

Yes, they start on Starter with 3: Slack, PagerDuty, webhooks and the other channels. Free has none, though visitors can still subscribe to its page by email, Slack, Teams or webhook.

Does the MCP server work on Free?

No. It runs on the public API, which starts on Starter. Connecting an AI agent from a Free organization starts a 14-day Starter trial, once per organization, with no card.

Can viewers sign in to a private page?

Yes, on Business and Enterprise: they sign in with Google or Microsoft, and you list the email addresses or domains allowed in. Enterprise adds your own identity provider, such as Okta, Entra ID or Auth0, over OpenID Connect.

Are API limits per key?

No, per organization: every key shares one daily quota, 10,000 requests on Starter, 100,000 on Pro and 500,000 on Business, plus 1,000 requests per minute. Enterprise has no limit.

Can I use Observer from a coding agent on the Free plan?

Yes. Coding agents (Claude Code, Cursor, Codex) and other MCP clients connect to Observer's MCP server on every plan. On Free they can make up to 500 requests a day, enough to install the agent, set up checks and ask about status; paid plans share the plan's API quota.

Is there an offer for early customers?

Yes. Teams whose customers hold them to SLAs can join the design partner program: three months free, then half price for the first annual year, in exchange for regular feedback. Apply at use.observer/design-partners.

Can I change plans later?

Yes, at any time. If a downgrade leaves you over a limit, you have 7 days to choose what stays active. After that the extra items are paused, never deleted, and upgrading again brings them back.
