Salesforce-owned PaaS for deploying web apps via git with dyno-based compute, managed add-ons (Postgres, Redis), and a rich ecosystem of third-party add-ons.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Config vars encrypted at rest; Heroku Private Spaces for network isolation (additional cost). SOC2 Type II certified.
⚡ Reliability
Best When
You have existing Heroku-deployed apps and need API-driven management, or are in Salesforce ecosystem where Heroku integration is native.
Avoid When
Starting a new project — Railway, Render, or Fly.io offer better value, performance, and features for equivalent or lower cost.
Use Cases
- • Deploying full-stack web applications with automatic scaling via dyno formation
- • Managing app lifecycle (create, deploy, scale, restart) programmatically via API
- • Provisioning and managing database add-ons (Heroku Postgres, Redis) via API
- • Running background workers and scheduled tasks with dyno types
- • Legacy app hosting where Heroku buildpack ecosystem simplifies deployment
Not For
- • Cost-sensitive workloads (Heroku is significantly more expensive than alternatives)
- • Applications needing GPU compute or specialized hardware
- • Teams wanting latest infrastructure innovation (Heroku has fallen behind competitors)
Interface
Authentication
API key via Authorization: Bearer header. OAuth for third-party integrations with scope-based access. Direct authorization header also accepted.
Pricing
No free tier since 2022. Add-ons billed separately. Heroku Postgres from $5/month (hobby) to hundreds for production.
Agent Metadata
Known Gotchas
- ⚠ Dyno formation scale-to-zero not native — dynos sleep on eco tier after 30min inactivity with cold start penalty
- ⚠ Release phase must complete successfully before app accepts traffic — track release status via releases endpoint
- ⚠ Config var changes trigger automatic restart — batch all env var changes in one PATCH request
- ⚠ Add-on attachment names differ from add-on plan names; use attachment name for DATABASE_URL env var lookup
- ⚠ Pipeline promotions via API don't wait for slug build — must poll pipeline-couplings for promotion completion
