When Salesforce admins hear "customer portal," most of us picture Experience Cloud first. It is the native answer: customers sign in to a branded site, open their own cases, and read Knowledge articles, all against your live org data.
But the native answer is not always the right answer for every team. Licensing costs, admin capacity, design freedom, or a business unit that already runs on another stack can all push you to look elsewhere. The trouble is that most roundups of Experience Cloud replacements read like feature bingo, and almost every product ticks almost every box.
There is a better way to judge them. Instead of comparing features, ask two questions that sit underneath the whole decision: where does the portal keep customer data, and what are portal customers in Salesforce's eyes? Those two answers decide what you pay Salesforce and how the whole thing behaves when it breaks. I first mapped this out in the original long-form piece at Way2Force, and this post is the condensed, hands-on version for admins and developers.
Four places a portal can live
1. On the platform: Experience Cloud and its ecosystem
This is the starting point rather than a true alternative. Every customer is a licensed external user: Customer Community for high-volume self-service, Customer Community Plus when you need roles and sharing rules, Partner Community for channel users with leads and opportunities, plus a few narrower license types for edge cases.
Some tools that appear on "alternatives" lists actually live here. Advanced Communities adds components on top of Experience Cloud and still requires an Experience Cloud license. There is also a headless flavor: your own React or mobile front end that signs customers in through Salesforce's headless identity APIs, keeping them licensed external users governed by the sharing model.
Why teams stay: there is no second copy of anything. When an agent closes a case at 4:55 p.m., the portal shows it closed at 4:55 p.m., because it is the same record. Security is enforced by the platform itself, so profiles, permission sets, sharing rules, login history, and Shield event monitoring (if you own it) cover external users too. Knowledge articles and Service Cloud cases work against live data from day one, and newer Agentforce self-service components slot straight into the site.
The price you pay: every customer needs a license, and every configuration change needs Salesforce skills. Guest access deserves particular respect, because researchers have repeatedly found Experience Cloud sites exposing private records to anonymous visitors through overly generous guest permissions. Salesforce has tightened the defaults since — guest users now receive records only through read-only guest sharing rules, and the external org-wide default for guests is forced to Private. Those protections help, but the platform enforces the design you build, not the design you meant.
2. Off-platform with a live connection
These portals live outside Salesforce and read and write your org's records on demand through a connected app, keeping no copy of their own. CRMJetty is one example of this pattern. Salesforce stays the system of record, portal users do not consume Salesforce licenses, and the site can be configured without touching Experience Builder.
The big bill here is the API budget. An Enterprise org gets 100,000 API calls per rolling 24 hours plus 1,000 per full Salesforce or Salesforce Platform license; Customer Community Plus and Partner Community add 200 each, while plain Customer Community adds nothing. Do the rough math: 1,000 customers loading ten pages a day at three calls a page is 30,000 calls — drawn from the same pool your other integrations drink from. Ask every vendor how many calls a typical page costs and whether it caches.
Then there is connection security. In August 2025, attackers used OAuth tokens stolen from the Salesloft Drift integration to export data from Salesforce instances at more than 700 organizations, according to Google's threat-intelligence team. Nobody broke into Salesforce; they rode a trusted connection. So ask what permissions the integration user holds, where tokens are stored, how you would revoke them in an emergency, and whether the connected app is installed in your org — since September 2025, Salesforce blocks most users from authorizing uninstalled connected apps.
One more subtlety: visibility rules live in the vendor's layer here, because customers are not Salesforce users. Your access-control review must cover the portal's configuration, not just your org's. Test it like an attacker would: sign in as one customer and try to open another customer's record by changing an ID in the URL.
3. Off-platform with a synced copy
These products keep their own database and refresh it from Salesforce on a schedule. Magentrix mirrors CRM records into its own platform, no-code builders like Knack run on their own database, and community platforms like Higher Logic Vanilla sync through a connector or Zapier.
The appeal: pages load from local data, the portal keeps working through a Salesforce outage, and page views do not spend your API budget. The costs: freshness — a few hours of lag is invisible on a knowledge base and unacceptable on case or order status, so ask for the sync interval per object, not as a headline number. Writes can collide when a customer and an agent edit the same record at once, so ask which edit wins and who gets told. And every mirrored record is a second copy of customer data that you must secure, retain, and delete when asked.
4. A different system of record entirely
Microsoft Power Pages, for example, builds portals on Dataverse — Microsoft's data platform, not Salesforce. This only belongs on the shortlist if you are moving customer data off Salesforce or part of the business already runs on Dynamics 365. Otherwise you are adopting a whole second platform, and the portal is the smallest part of that decision.
Five questions that place any vendor on the map
Before the feature grid, put these to every option, including Experience Cloud:
- After a customer views a record, where does it live — your org only, the vendor's database, or both?
- Who is the customer in Salesforce's eyes — a licensed external user, or someone represented by an integration user?
- What enforces record visibility — the Salesforce sharing model, or the vendor's access layer? If the vendor's, ask to see the configuration and the testing.
- What does a typical page cost in API calls — or how stale can the data get? Every off-platform option spends one or the other.
- What happens when the connection fails, and how do you revoke it? Walk through planned Salesforce maintenance and an expired token first.
These answers narrow a long shortlist to two or three serious contenders faster than any comparison table.
The short version
Experience Cloud is the only option where the portal and the CRM are literally the same system, and for teams with in-house Salesforce skills that is often the deciding advantage. Alternatives do not erase the work Experience Cloud does — they relocate it. A live connection shifts it to API budgeting and connection security; a synced copy shifts it to reconciliation and data governance. Choose the architecture whose chores your team is best equipped to handle, then compare features inside that lane.
