Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Gloo

  • Churches are not the paying customer, so the product roadmap answers to ministries, funders and campaign buyers whose interests do not always match a local congregation.
  • Participation routes congregant and enquirer interactions through a commercial data network, and a church board should have the data terms reviewed before enrolling a congregation rather than after.
  • It is not a church management system: there is no membership database, giving ledger, child check-in or rostering, so it sits alongside an existing ChMS rather than replacing one.
  • Free message credits are capped monthly, and a church that builds its weekly communications on texting will exceed them and move to paid volume where the effective cost is comparable to dedicated messaging vendors.
  • The company has grown by acquiring more than twenty brands, and integrating that many products takes time, so overlap and inconsistency between the acquired tools is visible to users.

Rock RMS

  • Non-traditional pricing model based on donations rather than standard software licenses
  • Pricing based on self-reported average weekend attendance with honor system
  • Grant applications required for churches unable to afford donations
  • Cloud hosting fees may apply separately to donation amount

Answered from the vendors’ own pages

Gloo: Is this the same as Gloo Gateway the API product?

No. This is gloo.com, the faith sector data and AI platform. Gloo Gateway is an unrelated API gateway product from a different company.

Rock RMS: How much does Rock RMS cost?

Rock operates on a donation model of $4.45 per average weekend attendee per year. Example: 100-person congregation = $445 annual commitment. No contracts, license fees, or hidden costs.

Source
Gloo: Why is it free for churches?

Because churches are not the revenue source. Ministries, publishers, philanthropists and campaign funders pay to reach and measure engagement with the audience the network reaches.

Rock RMS: What if a church cannot afford the donation?

Grant applications are available for churches unable to donate. Rock also offers alternative donation models for non-church nonprofits.

Source
Gloo: Does it replace our church management software?

No. There is no membership ledger, giving records, check-in or volunteer rostering. Keep your ChMS.

Rock RMS: Does Rock charge for cloud hosting?

Cloud-hosted churches combine the donation with hosting fees into a single monthly payment. Rock Cloud and Cloud 9 partner-hosted options are available with integrated billing.

Source
Gloo: What happens to data about people who contact us through Explorer?

That is the question to put in writing to Gloo before joining. Enquirer data flows through a commercial network, and the governing terms should be reviewed by whoever advises your board.
