The short version

  • Only Firebase has a free tier, so it costs nothing to try first.
  • Each has a real cost: Emerge Tools the value is proportional to application size and team size, so a small app learns what is wrong once and then pays a recurring subscription for a number that barely moves.; Firebase spark plan limited to 1 GiB storage, 50,000 daily reads, 20,000 daily writes
  • They diverge on capability: Emerge Tools covers Size diff on pull requests, Firebase covers Real-time Database.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Emerge Tools

  • The value is proportional to application size and team size, so a small app learns what is wrong once and then pays a recurring subscription for a number that barely moves.
  • Dead code detection depends on shipping instrumentation into production builds to observe which code real users execute, which several organisations refuse on privacy or performance grounds.
  • Pricing is quoted per application, so companies with a portfolio of apps face a multiplied cost that is difficult to justify outside the flagship product.
  • Uploading release binaries to a third party is a supply chain and confidentiality question that security review will raise, and it delays procurement more than the price does.
  • It measures and reports but does not fix anything, so the subscription only pays back if the team has capacity to act on the findings, which is exactly the capacity such teams tend to lack.

Firebase

  • Spark plan limited to 1 GiB storage, 50,000 daily reads, 20,000 daily writes
  • Spark plan restricts to 100 concurrent database connections
  • Spark plan limits Firebase Studio to 3 workspaces maximum
  • Document size capped at 1 MiB per document
  • Transaction time limited to 270 seconds with 60-second idle expiration
  • Maximum 100 databases per project (increase requires support request)

Emerge Tools

On request
  • Emerge Tools$undefined/year
    • Quoted per application per year, with the size analysis, performance and dead code products priced separately
    • Free analysis of a single build is offered publicly, which is enough to decide whether the problem exists

Firebase

  • SparkFree
    • No-cost usage with daily-refreshing quotas
    • Cloud Firestore: up to 1 GB storage, 20K writes/day, 50K reads/day
    • Cloud Functions: up to 2M invocations/month, 400K GB-seconds/month
  • Blaze$null/variable
    • Pay-as-you-go usage beyond free tier

Answered from the vendors’ own pages

Emerge Tools: Does app size really affect installs?

Yes, measurably on Android and in markets with constrained data. The size of the effect depends on your audience, which is why per app measurement is the point.

Firebase: What are Firebase's free tier limits?

Firebase Spark plan includes no-cost daily-refreshing quotas: Cloud Firestore up to 1 GB storage with 20K writes and 50K reads per day; Cloud Functions up to 2M invocations monthly; Cloud Storage 5 GB-months with 100 GB downloads monthly; Hosting 10 GB storage and 360 MB daily data transfer; Realtime Database up to 1 GB storage. No payment method required.

Emerge Tools: Do we have to upload our binary?

Yes, analysis runs on the build artefact. Expect a security review before procurement completes.

Firebase: How much does Firebase Blaze plan cost?

Firebase Blaze is pay-as-you-go beyond free tier limits. Pricing includes Cloud Firestore storage at $5/GB after 1 GB; Cloud Functions $0.40 per million invocations beyond 2M monthly; Cloud Storage $0.026/GB beyond 5 GB; Hosting $0.15/GB beyond 360 MB daily. New eligible customers receive $300 free credit.

Emerge Tools: Is this a replacement for crash reporting?

No. It covers size, launch performance and snapshots. Crash and error monitoring is a separate purchase.

Firebase: Which Firebase services are always free regardless of tier?

A/B Testing, Analytics, App Check, Cloud Messaging, and Crashlytics are offered at no cost on both Spark and Blaze plans, with no usage limits stated.
