The short version

  • Only Gloo has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Overflow crypto carries a 3 percent fee on top of the base rate, which makes it the most expensive channel on the platform at exactly the point where donors expect it to be cheap.
  • They diverge on capability: Gloo covers Gloo Workspace, Overflow covers Stock donation flow.
  • Prices and features above were last checked on 1 September 2026.

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.

Overflow

  • Crypto carries a 3 percent fee on top of the base rate, which makes it the most expensive channel on the platform at exactly the point where donors expect it to be cheap.
  • Card processing at 2.75 percent plus 30 cents on the entry plan is above what a church can get from a dedicated church giving processor, so using Overflow for routine weekly giving costs more than it should.
  • It is a giving channel, not a church management system, so contributions must be reconciled into your existing ChMS and finance software, adding a second monthly close step.
  • Stock and DAF fees are quoted as a 1 to 3 percent range with the actual rate depending on transfer route, so an organisation cannot forecast net proceeds precisely before the gift settles.
  • Non-cash gifts settle over days rather than instantly, and the amount received depends on the price at liquidation, so the receipted value and the cash landed will not match.

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.

Overflow: What does Overflow cost?

Foundation is 50 USD a month. Cards start at 2.75 percent plus 0.30, ACH at 0.50 percent plus 0.20, stock and DAF at 1 to 3 percent, and crypto adds 3 percent.

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.

Overflow: Why give stock instead of cash?

Transferring appreciated shares avoids the capital gains tax the donor would pay on selling first, so the same after-tax cost produces a larger gift.

Gloo: Does it replace our church management software?

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

Overflow: Does Overflow replace our church management system?

No. It handles giving only and integrates with your existing ChMS.

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.

Overflow: Do we hold the cryptocurrency?

No. Crypto gifts are liquidated and remitted as cash, so the organisation does not carry price risk after settlement.
