Lucity vs Heroku: Open-Source Heroku Alternative

Heroku invented the modern PaaS. git push heroku main changed how we deploy software. But that was 2009. A lot has happened since then.

Where Heroku Excels

Credit where it's due. Heroku earned its place in developer history:

• Pioneered the PaaS model: Heroku showed the world that developers shouldn't need to manage servers to deploy applications. Every PaaS since, including Lucity, owes something to that vision.
• Massive add-on ecosystem: databases, monitoring, logging, search, email. Heroku's marketplace has add-ons for nearly everything. Decades of ecosystem growth.
• Enterprise features: Salesforce integration, private spaces, Shield for compliance. If you're in the Salesforce ecosystem, Heroku has deep integrations nobody else offers.
• Battle-tested at scale: Heroku has run millions of applications. The platform has seen every edge case, every failure mode, every scaling challenge.
• Familiar to millions: so many developers learned deployment through Heroku. That institutional knowledge has enormous value.

Where Lucity Differs

Modern Architecture

Heroku runs on an aging infrastructure. Dynos, buildpacks, a proprietary runtime, all architecture decisions made in a different era of cloud computing. Heroku Postgres is solid but aging. The routing layer has known limitations. Scheduling and background workers require bolt-on add-ons.

Lucity is built on Kubernetes, Helm, CloudNativePG, and Gateway API: the tools the cloud-native ecosystem has converged on over the past decade. These aren't trendy choices; they're industry standards with massive communities, extensive documentation, and long-term support.

The ecosystem moved on. Your platform should too.

Pricing

Heroku's pricing has become increasingly enterprise-focused since the Salesforce acquisition. The free tier is gone. Basic dynos start at $7/month with limited features. Production-grade setups with proper databases, logging, and monitoring add up quickly. And those add-ons? Each one has its own pricing tier.

Lucity is open source. Self-host on your own cluster and pay only for the compute you actually use. No per-dyno pricing. No add-on surcharges. No "you need Professional dynos to get preboot" upsells.

If you'd rather not manage infrastructure, Lucity Cloud offers managed hosting with transparent pricing. But the self-hosted option is always there. A sentence Heroku literally cannot say.

Ejectability

Heroku gives you buildpacks and a Procfile. If you leave, you take your source code and start rebuilding everything from scratch: deployment pipelines, environment configurations, database provisioning, service discovery, monitoring setup.

Lucity gives you standard Helm charts and values. lucity eject produces everything you need to run independently: the chart, the values for each environment, your databases and buckets as standard operator resources, and a setup guide. No Lucity dependencies, no proprietary formats, no migration project.

Leaving Heroku is a quarter-long project. Leaving Lucity is a command.

Open Source

Heroku is proprietary, owned by Salesforce. You can't see the code, can't self-host, can't modify it. When Salesforce decides to change pricing, sunset features, or shift strategic direction (and they have, repeatedly), your options are to accept it or migrate.

Lucity is AGPL-3.0. The code is public, auditable, and forkable. Run it yourself, contribute improvements, or just read the source when something behaves unexpectedly. Open source means you're a participant, not just a customer.

Declarative Releases

Heroku deploys from Git pushes, which was revolutionary in 2009. But the result is a slug on Heroku's runtime, not a declarative description you own. There's no portable desired state and no history you can read outside Heroku's tooling.

Lucity deploys every project as a standard Helm release per environment, with the state stored in your cluster. Every change is a new release revision. Promote between environments by copying the image digest, with no rebuild. Roll back by re-applying a previous revision. See what was deployed and when with helm history. It's deployment management that works with tools your team already knows.

Who Should Choose Heroku

• Enterprises already deep in the Salesforce ecosystem
• Teams that need Heroku's mature add-on marketplace for specific integrations
• Developers who value familiarity and don't want to learn new tools
• Projects where Heroku Shield's compliance features (HIPAA, PCI) are specifically needed

Who Should Choose Lucity

• Teams that want a modern PaaS without the Salesforce tax
• Teams that care about open source, self-hosting, or data residency
• Teams that want ejectability: the ability to leave without a migration project
• Developers who want to learn Kubernetes organically, not as a crisis response
• Cost-conscious teams that want to self-host and pay only for compute
