# Supabase vs Firebase

Supabase released OrioleDB, Multigres, and the Explorer editor within three days, while Firebase made App Check mandatory for its AI Logic features and promoted agent integrations; both companies are courting AI coding tools, and the report offers no evidence yet on which platform is winning.

# Supabase vs Firebase: Research comparison

## Quick Verdict

Supabase still carries the page title "The Open Source Firebase Alternative" on [supabase.io](https://supabase.io/), and on October 21 [@Firebase](https://x.com/Firebase/status/2112955209496306038) promoted SQL Connect as a way to "generate a secure PostgreSQL schema." The two products now overlap more than their old SQL-versus-NoSQL framing suggests. On scale, [supabase/supabase](https://github.com/supabase/supabase) has 114,466 GitHub stars and 1,161 open issues. The auto-generated transcript of [Y Combinator's "When Agents Become Your Users"](https://www.youtube.com/watch?v=vl7HiMdGfjo) interview (72,866 views) says Supabase "now has 13 million users and it's spinning up over a million databases a week." The gathered evidence has no platform user count for Firebase. Its three SDK repos ([iOS](https://github.com/firebase/firebase-ios-sdk) 6,979, [JS](https://github.com/firebase/firebase-js-sdk) 5,157, [Android](https://github.com/firebase/firebase-android-sdk) 2,580 stars) measure client libraries rather than the platform, so the star gap is not a like-for-like comparison. The month's evidence shows both companies courting AI coding agents, with Firebase's own docs now framing [AI-assisted setup](https://firebase.google.com/docs/ai-assistance/build-with-ai) as a first-class workflow using Antigravity, Claude Code, Codex, and Cursor through agent skills, the Firebase CLI, and an MCP server. It does not include migration data showing which one is winning.

## Supabase

**Supabase shipped three Postgres launches in three days: OrioleDB in public beta on every plan (October 28), Multigres in private alpha (October 29), and the Explorer query editor (October 30).** [@supabase](https://x.com/supabase/status/2115849903427502490) described Multigres (149 likes) as "high availability for Supabase Postgres," with automatic standby failover. The [official Multigres docs](https://supabase.com/docs/guides/database/multigres) describe it as an "operating system for Postgres" that runs across multiple nodes with automatic failover, free during the Alpha for paid-plan organizations but capped at two projects per org and explicitly not covered by Supabase's [uptime SLA](https://supabase.com/sla). The [changelog entry](https://supabase.com/changelog/multigres-private-alpha) confirms the October 1 private-alpha opening, and Supabase's earlier [Multigres v0.1 Alpha blog post](https://supabase.com/blog/multigres-v0-1-alpha) traces the project back to a June 4 open-source release built with Vitess creator Sugu Sougoumarane, pitching "Vitess-grade horizontal scaling, high availability, and operational simplicity" for Postgres. Access is limited to paid-plan organizations that request it, so this is not a general release. Explorer (142 likes) adds Notebooks that "your agent" can run. The [Supabase Select recap](https://www.youtube.com/watch?v=I9GymvCJRRw) (30,061 views) opens with Supabase having "purchased Turso, the SQLite company," and introduces Supabase Compute, which reached [Hacker News](https://supabase.com/blog/supabase-compute-private-alpha) as a private alpha with 4 points.

Practitioner sentiment on the database layer is positive. In a [r/nextjs](https://www.reddit.com/r/nextjs/comments/1x8nbjc/anyone_building_databaseheavy_sites_with_nextjs/) thread (17 points, 34 comments), u/TheYawningRapport wrote that "Supabase works pretty well for the database side," and warned that unindexed filters get painful past roughly 50k rows. [Dave Ebbelaar's](https://www.youtube.com/watch?v=XzjSx7u9mGw) full-stack AI course built on Supabase drew 73,315 views. [Product Hunt](https://www.producthunt.com/products/supabase/reviews?filter=founder&founderReview=315331&page=1) shows 912 reviews averaging 5.0. A [brycent](https://www.instagram.com/reel/DeGHMJstBIr/) reel (4,234 likes) cites a $10.6B valuation. On pricing, Supabase's [own pricing page](https://supabase.com/pricing) lists a Free tier (unlimited API requests, 50,000 monthly active users, 500 MB database), Pro at $25/month (100,000 monthly active users), and a Team tier at $599/month aimed at organizations needing advanced collaboration and compliance controls, per [No Code MBA's 2026 breakdown](https://www.nocode.mba/articles/supabase-pricing) and the independent pricing tracker [Tierpeek](https://tierpeek.com/pricing-changes/company/supabase). A third-party calculator from [MakerKit](https://makerkit.dev/blog/saas/supabase-pricing) estimates a mid-size workload landing around $25 base plus $50 compute for a Medium instance, before storage and egress are added, and notes that Team and Enterprise base fees aren't published. The company is also hiring heavily: 69 roles appear on its Ashby board, including a [Software Engineer - AI Tooling Infrastructure](https://jobs.ashbyhq.com/supabase/fb0b563a-e541-43fd-8555-9eb6473aaa11), a [Product Manager - Administration & Governance](https://jobs.ashbyhq.com/supabase/c20228c2-45ff-4b77-ab77-906f39a06ca3), and [Database Support Engineer](https://jobs.ashbyhq.com/supabase/f18b1173-51c3-4ff6-bcda-89f8111931f4) seats across regions. Each listing pitches Database, Auth, Storage, Edge Functions, Realtime, and Vector Search as one integrated platform.

The weaknesses cluster around security mistakes made by AI-assisted builders, plus cost. A [r/Supabase](https://www.reddit.com/r/Supabase/comments/1xee4qx/i_checked_5000_public_bolt_supabase_repos_for_rls/) audit (12 points, 20 comments) found that 26% of about 5,000 public Bolt + Supabase repos have a table anyone can read. Commenter u/Personal_General_725 challenged how repos were attributed to Bolt. Separately, [rekavigwebdesign](https://www.tiktok.com/@rekavigwebdesign/video/7703657449190067458) and [rowattest](https://www.tiktok.com/@rowattest/video/7701336926439230728) posted RLS leak tutorials, and [ctrlztherapy](https://www.instagram.com/reel/DeKH1eiAIBo/) explained that Edge Function secrets stay on the server, so a visible key means it was exposed through a VITE_ or NEXT_PUBLIC_ variable.

On cost, a [video-egress thread](https://www.reddit.com/r/Supabase/comments/1xffl6o/how_can_i_reduce_supabase_egress_costs_for_a/) (31 comments) produced u/WarmDrunkenness5's line that "videos will eat your egress for breakfast." A [r/vibecoding](https://www.reddit.com/r/vibecoding/comments/1x0h0ko/do_not_use_supabase_fellow_vibe_coders/) "DO NOT USE SUPABASE" post drew 74 comments, but the top reply from u/TheAnswerWithinUs (51 upvotes) mocked the poster instead of agreeing. [John Kealy](https://www.youtube.com/watch?v=JllzgqiOF34) (9,821 views) argues that "every tutorial you've ever watched about Supabase is totally wrong."

## Firebase

**On November 2, @Firebase made App Check enforcement mandatory for Firebase AI Logic and pushed a plugin into @Antigravity's new Marketplace.** The [Marketplace post](https://x.com/Firebase/status/2117361882453483947) (144 likes) says the plugin offers agent guidance to secure Firestore rules, deploy to App Hosting, and set up AI logic. The [App Check post](https://x.com/Firebase/status/2117310980392730800) (7,332 views) means generative features need attestation configured to keep running. This lines up with [Firebase's official AI-assistance documentation](https://firebase.google.com/docs/ai-assistance/build-with-ai), which now positions Firebase agent skills, the Firebase CLI, and a dedicated Firebase MCP server as the recommended way to wire Antigravity, Claude Code, Codex, or Cursor into a Firebase backend. Firebase's October output leaned heavily toward agents: [Agent Skills for Firebase](https://x.com/Firebase/status/2113678253625913549) with Antigravity CLI (63 likes), a [six-hour iOS app build](https://x.com/Firebase/status/2114757724835635406) using Antigravity (50 likes), and [Gemini API calls through AI Logic](https://x.com/Firebase/status/2116215599596507268) (6,731 views).

Strengths show up in mobile and budget tooling. The September [Release Notes](https://x.com/Firebase/status/2107894842491850920) (67 likes) lead with Spend Caps in public preview. [Phone Number Verification](https://x.com/Firebase/status/2115494787629412716), which offers carrier-level checks instead of SMS OTPs, drew 149 likes. At FlutterCon, Firebase's Arthur Thompson appeared on the [Flutter and Firebase](https://www.youtube.com/watch?v=CcyX-pqjDp0) channel (9,246 views). Notably, the interviewer raised the perception that developers "outgrow Firebase." [mr_mewhy](https://www.threads.com/@mr_mewhy/post/DejsJbRk7Y4) (54 likes) shipped 4 web apps on the free Spark Plan. Developers are also building tools around the platform. The [hidane 0.1.0](https://www.reddit.com/r/Firebase/comments/1x30udf/hidane_010_a_firestore_emulator_without_java_that/) Java-free Firestore emulator post got 7 points on [r/Firebase](https://www.reddit.com/r/Firebase/comments/1x30udf/hidane_010_a_firestore_emulator_without_java_that/). [Aruma](https://github.com/arumadev/aruma), a self-hosted backend for the official SDKs that pitches a "~$5 VPS," got 3 points on HN.

The weaknesses are reliability and quota surprises:

- **Realtime Database incident.** The [Firebase Status Dashboard](https://status.firebase.google.com/incidents/9xsJMtCjjVuSHugHs8Zc) logged partial RTDB degradation in us-central1 on October 21. [IsDown](https://isdown.app/status/firebase/incidents/673737-partial-performance-degradation-for-rtdb-users-in-us-central1)'s AI summary describes intermittent 500 errors lasting over 24 hours.
- **Outage count.** [incidenthub](https://incidenthub.cloud/status/firebase) claims 7 outages in 30 days. [StatusGator's Firebase Platform page](https://statusgator.com/services/firebase/firebase-platform) also tracks user-reported issues.
- **SDK churn.** [JS SDK 13.0.0](https://firebase.google.com/support/release-notes/js) (October 7) carried a breaking AI Logic change, and 13.1.0 fixed transient Auth 5xx errors.
- **Auth quota.** A [r/Firebase](https://www.reddit.com/r/Firebase/comments/1xll6i6/firebase_auth_hitting_a_200day_getoobcode_quota/) post (3 points, 9 comments) reports a 200/day GetOobCode quota blocking verification emails on Blaze.
- **Architecture caution.** [ayesha.appdev](https://www.threads.com/@ayesha.appdev/post/DfO7D10jg5T) summed it up: "Firebase can speed up development, but it won't fix poor architecture."

## Head-to-Head

| Trust signal | 912 Product Hunt reviews averaging 5.0 | 385 open roles listing Firebase as a skill on CareerHolo |

## The Bottom Line

Choose Supabase if your data is relational, you ship web apps on Next.js or Vercel, and you are willing to own your RLS policies instead of trusting AI-generated ones. The [r/nextjs](https://www.reddit.com/r/nextjs/comments/1x8nbjc/anyone_building_databaseheavy_sites_with_nextjs/) consensus is that the Postgres underneath holds up well if you index early. The 26% open-table audit shows the cost of skipping that work. Media-heavy apps should plan to offload files, as u/Ok-Motor-9812 (7 upvotes) did with Cloudflare R2. Budget planning matters too: Supabase's own [pricing page](https://supabase.com/pricing) and third-party trackers like [Tierpeek](https://tierpeek.com/pricing-changes/company/supabase) and [MakerKit](https://makerkit.dev/blog/saas/supabase-pricing) show costs climbing quickly past the Free tier once compute, storage, and monthly active users scale up, and Supabase's own [billing FAQ](https://supabase.com/docs/guides/platform/billing-faq) explains that pricing is organized around organizations containing multiple projects, each billed for its own compute and add-ons.

Choose Firebase if you are building mobile-first apps with Flutter, iOS, Android or React Native and want Gemini wired in through AI Logic and Google's agent plugins. [@Firebase](https://x.com/Firebase/status/2114757724835635406) is clearly investing in that path, and its [AI-assistance docs](https://firebase.google.com/docs/ai-assistance/build-with-ai) now formalize that investment with agent skills and an MCP server built for coding agents. Do two things before committing: test Auth email quotas on Blaze, given the [GetOobCode thread](https://www.reddit.com/r/Firebase/comments/1xll6i6/firebase_auth_hitting_a_200day_getoobcode_quota/), and set up App Check before relying on AI features. Demand for the skill is real: [CareerHolo's Firebase Jobs page](https://careerholo.com/jobs/skill-firebase) counts 385 openings with a $175k median, though [TheJobsMap](https://www.thejobsmap.com/company/firebase) lists no open roles at Firebase itself as of November 2.

## The emerging stack

The gathered evidence does not establish anyone running Supabase and Firebase together. When [junky_rd](https://www.threads.com/@junky_rd/post/DesFgGvEw8v) asked whether to "use firebase or supabasss," the choice was framed as either/or. What does repeat is a three-layer pattern of agent, frontend host, and backend, with each platform in the backend slot:

- **Supabase variants.** [bstratgie.web.aca](https://www.tiktok.com/@bstratgie.web.aca/video/7703540589022678290) tells Claude Code users to install Supabase and Vercel plugins first. [hisyamhamzahhh](https://www.threads.com/@hisyamhamzahhh/post/DfJrE4jk9hi) (64 likes) built on Claude AI Pro + Supabase + Netlify. [_nexa_byte](https://www.tiktok.com/@_nexa_byte/video/7703647334772542740) lists React Native, Next.js, Vercel and Supabase. [draguuu](https://www.threads.com/@draguuu/post/DfIt74TGPAw) (10 likes) asked whether Vercel + Supabase is a solid foundation to grow on.
- **Firebase variants.** [mr_mewhy](https://www.threads.com/@mr_mewhy/post/DejsJbRk7Y4) runs VS Code, then Firebase, then GitHub, then Netlify. @Firebase's own showcase pairs Firebase with Antigravity, and its [AI-assistance docs](https://firebase.google.com/docs/ai-assistance/build-with-ai) now explicitly add Codex and Cursor to that pairing.

So the real contest is less Postgres versus Firestore than which backend the coding agent reaches for by default.
