Firebase Blaze alternatives: 8 open-source picks
These 8 Firebase Blaze alternatives replace it for $0, led by Supabase, PocketBase and Appwrite. All 8 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
A local, self-hosted backend with emulators-by-Docker: database, auth, storage, realtime, functions, and APIs.
licenseApache-2.0
runsyour machine or their cloud
installHosted Supabase project, or the official Docker Compose stack; `supabase start` runs the local stack
dataRelational data, auth records, and platform metadata live in PostgreSQL; Realtime consumes the Postgres replication stream; object data lives in the configured storage backend with metadata in Postgres; edge-function and migration source stays in project files. Supabase Cloud stores and operates the managed copy.
the catch vs Firebase BlazeSupabase is the broadest substitute, but Firebase still has the tighter mobile SDK, offline sync, Analytics, Crashlytics, Cloud Messaging, Remote Config, and Google-service integration.
setupSelf-hosting is not 'just Postgres': the Compose stack needs many secrets and services, plus SMTP, object storage, TLS, backups, observability, and coordinated upgrades.

For one modest app, a single local binary covers data, auth, files, realtime, and an admin UI; functions are the missing piece.
licenseMIT
runsyour server
installDownload one platform binary and run `pocketbase serve`; build from Go source only for custom extensions
dataCollections, auth records, settings, and application data live in SQLite files under `pb_data`; uploaded files live under `pb_data/storage` by default or in configured S3-compatible storage, and schema migrations can be kept as JavaScript files in `pb_migrations`.
the catch vs Firebase BlazePocketBase is excellent for one modest app, but a single SQLite server with no built-in functions runtime cannot match Firebase's offline SDKs, global scaling, messaging, analytics, or managed operations.
setupIt installs unusually cleanly, but a public deployment still needs process supervision, HTTPS/reverse proxying, backups of `pb_data`, and a deliberate upgrade routine.

Auth, database, storage, realtime, and functions behind one polished console; the Compose file is doing a lot.
licenseBSD-3-Clause
runsyour machine or their cloud
installHosted Appwrite Cloud signup, or the official Docker installer/Compose stack
dataSelf-hosted Appwrite stores application records in MariaDB, queues and cache in Redis, and uploaded files in Docker volumes or a configured object-storage adapter; functions and build artifacts are managed by the Appwrite worker/executor services. Appwrite Cloud stores the equivalent data in Appwrite's infrastructure.
the catch vs Firebase BlazeAppwrite covers auth, data, files, functions, and realtime, but it lacks Firebase's mature offline mobile SDKs, global managed scale, Analytics, Crashlytics, Messaging, and Google ecosystem.
setupThe installer is one command, but it expands into a large multi-container platform; production use still needs a domain, TLS, SMTP, storage, backups, and careful version upgrades.

Postgres plus GraphQL, auth, storage, functions, and realtime; closer to Firebase than most Firebase alternatives.
licenseMIT
runsyour machine or their cloud
installHosted Nhost project, or Nhost CLI/Docker for local and self-hosted deployments
dataApplication and auth records live in PostgreSQL, GraphQL metadata and migrations can live beside the project in version-controlled files, uploaded objects use S3-compatible storage, and serverless-function source remains in the project directory. Nhost Cloud runs those services in Nhost's infrastructure.
the catch vs Firebase BlazeNhost replaces Firebase with PostgreSQL and GraphQL, but gives up Firestore's offline-first client behavior, Google mobile services, global operational footprint, and breadth of first-party SDKs.
setupSelf-hosting means operating PostgreSQL, Hasura, authentication, storage, functions, networking, secrets, email, and upgrades rather than one small binary.

last updated 2026-08-29 · no votes, no pay-to-list · just what's real
how to choose a Firebase Blaze alternative
Easiest to get running
PocketBase — a one-click install, no server to maintain.
Most proven
Supabase, with 107,608 GitHub stars — the largest community of the 8, which usually means more answers when something breaks.
Needs real ops to self-host
Supabase and Nhost are capable but expect someone to run a server, updates and backups. Budget for that before choosing one.
what you give up by leaving Firebase Blaze
- global database, auth, push, analytics, serverless, mobile SDKs, and operations
- global edge network
- managed databases
- autoscaling
- DDoS protection, support, and compliance
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Firebase Blaze
People still pay for Firebase Blaze because hosting products sell an operations team and failure-domain diversity, not merely a deploy button. The recurring cost buys patching, certificates, isolation, secrets, builds, deploys, logs, metrics, backups, capacity, incidents, and security response, not just the visible interface.
