| Pricing | $0.0055 per MAU/month above 50,000 Tier 1 MAUs (Blaze plan, pay-as-you-go) · free tier: Spark plan: no payment method required; other authentication services (email, social, anonymous) included at no cost; Phone Auth listed as 'Not applicable'. With Identity Platform: 50,000 MAUs free and 50 SAML/OIDC MAUs free. | USD $5/month (Eco dyno, 0.5 GB, personal accounts only, sleeps after 30 minutes of inactivity); Heroku Postgres Essential-0 also $5/month · free tier: None on the published price list; Basic Support is free, and Heroku Connect has a free Demo Edition |
| Pricing model | Usage-based (two plans: no-cost Spark and pay-as-you-go Blaze) | Usage-based / resource-metered subscription (per dyno, per database, per token) |
| Best for | Consumer-facing mobile or web products with standard email/social/phone sign-in needs, especially teams already committed to Firestore or the wider Firebase/Google Cloud stack, and startups whose user base fits inside the 50,000 free MAU allowance. | Small-to-mid engineering teams, startups and agencies that want to ship without hiring a platform engineer, Salesforce-centric organisations needing Heroku Connect sync, and regulated workloads wanting HIPAA/PCI controls with PaaS convenience. |
| Avoid if | You sell enterprise SSO (SAML/OIDC billed at $0.015/MAU after 50 free users), need deep customization of login flows or fine-grained authorization, run high-volume SMS auth in expensive regions, require contractual data residency, a published SLA or a named compliance attestation, or have a hard multi-cloud portability mandate. | You are a hobbyist or student with no budget, run sustained high traffic where per-unit infrastructure cost dominates, need fast-turnaround support without an Enterprise contract, require low-level infrastructure control such as persistent local disk or custom cron daemons, or cannot work with credit-card-only monthly billing. |

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
