Heroku is a platform for running web apps, APIs and workers in languages such as Node.js, Python, Java and Ruby, with Heroku Postgres for data. Salesforce bought Heroku in 2010.

New to Heroku?
What is Heroku?
It is a separate platform from your Salesforce org. A Salesforce sandbox does not clone a Heroku app, and Heroku is not Data 360. The two are connected on purpose.
In February 2026 Heroku moved to a sustaining engineering model focused on stability, security, reliability and support, and stopped offering Enterprise Account contracts to new customers.
Where you are starting from
Should this app run on Heroku?
Heroku's 2026 move to sustaining engineering changes the advice for new apps. Apps already on Heroku keep running, and existing Enterprise contracts are honored.
What do you have today?
- Path 01An app already on Heroku
Run it well and connect it
Your app and your contract carry on. Start with a review of the app and its Salesforce connection.
- Runtime and database versions checked
- Heroku Connect or API sync reviewed
- Pipelines, logs and alerts in place
- Path 02A new app beside Salesforce
Compare platforms first
New customers can no longer sign Enterprise Account contracts, so a new build starts with a written platform comparison.
- Heroku, Experience Cloud and other clouds compared
- Data sync and sign-in needs listed
- Run and support model agreed
- Path 03Logic Salesforce should call
Consider Heroku AppLink
Heavy processing that Flow, Apex or Agentforce needs can run on Heroku and be called through AppLink.
- Actions defined for Flow builders
- Permissions set per action
- Errors returned to the caller
A written decision on where the app runs and how it connects to your org

Connections
Heroku Connect, Heroku AppLink or the Salesforce APIs?
Three ways to join a Heroku app to your org. Many apps use more than one.
Heroku Connect
- The app needs Salesforce records in its own database
- Best fit: sync to Postgres
- Salesforce needs to call code on Heroku
- Not its purpose
- Developers work in SQL
- Yes, against Postgres tables
- React to changes in Salesforce
- Scheduled sync, with accelerated polling
- Where the connection logic lives
- In the Heroku Connect add-on
Heroku AppLink
- The app needs Salesforce records in its own database
- Not its purpose
- Salesforce needs to call code on Heroku
- Best fit: actions for Flow, Apex and Agentforce
- Developers work in SQL
- No, through the AppLink SDK
- React to changes in Salesforce
- When Salesforce calls the action
- Where the connection logic lives
- In your Heroku app code
Salesforce APIs and events
- The app needs Salesforce records in its own database
- Works, with sync code you own
- Salesforce needs to call code on Heroku
- Works through custom callouts
- Developers work in SQL
- No, through API calls
- React to changes in Salesforce
- Change Data Capture and platform events
- Where the connection logic lives
- In your Heroku app code
Heroku Connect beyond the free demo plan is a contract plan. If you are new to Heroku, confirm with Salesforce that it is available to you before designing around it.
Heroku AppLink
How does Salesforce call a Heroku app through AppLink?
A quote needs pricing logic that is too heavy for Apex. A flow calls an action on Heroku and writes the result back to the quote.
- Sales rep
- Salesforce Flow
- Heroku AppLink
- Heroku app
- Salesforce records
- Sales rep to Salesforce Flow: Asks for a price
- Salesforce Flow to Heroku AppLink: Calls the published action
- Heroku AppLink to Heroku app: Passes the request with org context
- Heroku app to Salesforce records: Reads products and terms
- Heroku app to Heroku AppLink: Returns the result
- Heroku AppLink to Salesforce Flow: Hands back the price
- Salesforce Flow to Salesforce records: Writes the quote lines
- Salesforce Flow to Sales rep: Shows the quote for review

Cost and timing
What it costs and how long it takes
The review is free
A 60-minute architecture review of your Heroku and Salesforce setup, with a written plan you keep.
A fixed-scope proposal first
Before any work starts you get a written proposal: a fixed-scope project with milestones, or a monthly plan. You approve it, or you do not.
Timing follows scope
How long it takes depends on what is in scope. The proposal states the milestones, so you see the timeline before you commit.

Frequently asked questions
Heroku apps for Salesforce, answered.
Straight answers about Heroku's 2026 status, Heroku Connect, AppLink and supporting the apps you already run.
Building and supporting web apps, APIs and workers on Heroku that share data with Salesforce through Heroku Connect, Heroku AppLink or the Salesforce APIs, with pipelines, monitoring and a named owner.
Yes. In February 2026 Heroku moved to a sustaining engineering model focused on stability, security, reliability and support. Existing Enterprise subscriptions continue and may renew; new customers can no longer sign Enterprise Account contracts.
It depends on your contract and the app. Existing Enterprise customers can build inside their agreement. New customers should compare Heroku with Experience Cloud and other clouds first, and we write that comparison with you.
Salesforce bought Heroku in 2010, and Heroku is still a separate platform. A Salesforce sandbox does not clone a Heroku app, and Heroku is not Data 360.
A Heroku add-on that syncs Salesforce objects with Heroku Postgres tables, so developers can work in SQL. The free demo plan has a row limit; larger plans are contract plans.
An add-on, formerly called Heroku Integration, that exposes Heroku apps as API services in Salesforce, so Flow, Apex and Agentforce can call code that runs on Heroku.
Yes. We review runtime and database versions, pipelines, logs and the Salesforce connection, fix what is at risk, and can take on monthly upkeep as Heroku developers on your team.
No. Heroku and Salesforce set their own prices and contracts. Our written proposal covers our work only, as a fixed-scope project or a monthly plan.
