Insurance for outages, not migrations
The missing high-availability layer for Supabase.
The page makes FaaS feel like a native HA add-on rather than a generic backup tool: it sits in front of Supabase, handles edge routing, preserves auth, and syncs changes back.
An alternative to building your own failover stack with Cloudflare, PostgreSQL replication, and custom recovery logic.
The product explicitly says it is built on Cloudflare, AWS, Aurora, and Supabase, and abstracts away the hardest parts: health checks, rerouting, replay, and repair.
Insurance against Supabase outages, not another database migration project.
The copy emphasizes 'no code changes,' 'cancel anytime,' and 'your primary Supabase is always your source of truth,' which is a strong anti-lock-in, low-friction risk mitigation frame.
Primary user
Founding engineer or backend engineer at a SaaS startup running production on Supabase
ICP #1
CTO of a Seed-stage B2B SaaS company with a customer-facing app on Supabase
Pain
Every Supabase incident becomes a fire drill because the app, auth, and database all depend on one managed service with no built-in active-active failover.
Why this solves
FaaS gives them an always-on standby, automatic reroute, and write-back recovery without rebuilding their stack or adding DNS-based failover logic.
ICP #2
Staff engineer at a product-led startup shipping Next.js and mobile apps on Supabase
Pain
They need uptime guarantees but do not want to design and maintain their own replica, router, and recovery workflows across multiple clients.
Why this solves
FaaS claims transparent routing for Next.js, Flutter, and React Native plus full auth support, so the engineer keeps shipping instead of owning disaster recovery plumbing.
ICP #3
Founder-operator of a small SaaS with one engineer and no dedicated SRE
Pain
A single outage can mean lost sign-ins, lost writes, and angry customers, but they lack the bandwidth to build HA on top of Supabase.
Why this solves
FaaS is positioned as turnkey insurance: 3-step setup, managed provisioning, monitoring, failover, and recovery handled for them.
Strengths
- +The value proposition is crystal clear in the hero: zero-downtime failover specifically for Supabase.
- +The page goes deep on mechanism, not just benefits, with a concrete 5-second health check and ~15-second failover claim.
- +The Test Failover button and demo video are strong trust builders for a skeptical infrastructure buyer.
Weaknesses
- −The product name 'FaaS' is dangerously ambiguous because it already means Function as a Service in cloud infrastructure.
- −The page overclaims in places without enough proof, especially 'zero data loss,' 'full auth capability,' and 'self-healing replication' for real-world edge cases.
- −It is too enterprise-infrastructure heavy for a Supabase audience that may not immediately understand Aurora, EC2, or Cloudflare routing diagrams.
- −There is no obvious proof of reliability: no customer logos, no uptime stats, no benchmarks, no security audit, and no real-world incident examples.
- −Pricing is too thin for a mission-critical product; buyers will want clarity on limits, failover behavior, supported Supabase plans, and recovery semantics.
Fix these
- Rename or visually disambiguate the brand from generic 'FaaS' cloud terminology to avoid confusion in search and in conversation.
- Add a proof section with an end-to-end failover demo, timing screenshots, and a documented failure test from a real Supabase outage scenario.
- Translate the architecture into a simpler buyer story: 'protect your Supabase app without rewriting auth, APIs, or client code.'
- Add objection-handling content for engineers: RLS behavior, websocket/subscription behavior, OAuth edge cases, and what happens if standby lags primary.
- Introduce social proof and operational credibility: customer quotes, incident metrics, security posture details, and a clear SLA or reliability guarantee.

Headline
Keep Supabase up when it breaks
Managed hot-standby failover with automatic reroute and write-back sync.
Stay online through outages
FaaS keeps a warm standby ready and reroutes traffic automatically when your primary Supabase project goes down. Your users keep hitting one endpoint instead of a dead backend.
Recover writes, not just reads
Anything written during the outage gets replayed back to the primary when it recovers. That means less lost work, fewer support tickets, and a cleaner incident story.
Keep auth working during failover
OAuth and session flows keep working through the edge layer, so logins don’t become the first thing that breaks. That matters when your app depends on Supabase for both Postgres and auth.
Test the failure before it finds you
Use the Test Failover button to simulate an outage and see how the system behaves end to end. If you care about uptime, proving the path matters more than promising it.
FAQ
Does this require code changes?
No. FaaS is designed to sit in front of your Supabase project and route traffic transparently. Your app keeps using the same endpoint.
What happens to writes during an outage?
Writes made while the primary is down are captured on the standby path and replayed back when Supabase recovers. The exact recovery behavior depends on your workload, so test it before you rely on it.
Will auth still work?
It’s built to support auth flows, including major OAuth providers. If your setup has unusual auth edge cases, validate them with a failover test first.
How fast is failover?
Health checks run every 5 seconds and cutover is roughly 15 seconds in normal conditions. Real-world timing can vary with network conditions and workload.
Is this a replacement for Supabase?
No. Supabase remains the source of truth. FaaS is the high-availability layer in front of it, meant to reduce downtime without forcing a migration.
When Supabase flakes, your auth breaks, your writes fail, and your customers blame you. That’s the gap we built FaaS for: hot-standby failover for Supabase with automatic reroute + write-back sync. No DNS games. No code changes.
Supabase gives you a great backend. It does not give you a disaster recovery plan. FaaS sits in front of your project, keeps a warm standby ready, and flips traffic automatically when the primary goes down. Your app keeps serving.
We built a Test Failover button for a reason. Health checks run every 5 seconds. When the primary dies, traffic reroutes to the standby automatically. Then writes made during the outage get replayed back to Supabase when it recovers.
The hard part was write-back. Keeping reads up is easy. Keeping auth working is harder. Replaying writes safely after recovery is the part that actually hurts. That’s what we spent the most time on. Infrastructure is only interesting when it fails.
Every team says 'we'll add failover later.' Then one Supabase incident turns into a lost signup day, broken auth, and angry support tickets. FaaS is for the day you don't want to explain why the app was down with the database.
If you run a SaaS on Supabase, your real problem isn't Postgres. It's the blast radius: auth, writes, subscriptions, and mobile clients all break at once. FaaS reduces that to one endpoint and one recovery path.
FaaS is managed hot-standby failover for Supabase. It provisions a dedicated standby, keeps it synced, reroutes traffic on outage, and syncs recovered writes back to the primary. Basically: your Supabase goes down, your app stays up.
Single endpoint. Edge routing. Automatic failover. Then a failback path that replays writes to the primary when it comes back. That’s the whole product. Not sexy. Just useful when production is on fire.
We kept seeing the same pattern: teams love Supabase until they need uptime guarantees. So we built the layer nobody wants to build themselves: standby, routing, recovery, and write-back sync. If you’re shipping on Supabase, this is the missing piece.
Nobody wakes up wanting to manage Cloudflare, replication, health checks, and recovery scripts. They want their app to stay up when the primary breaks. That’s the promise here: no code changes, no DNS cutover, no new ops burden.
Angle: insurance against Supabase outages
If your SaaS runs on Supabase, you probably already know the uncomfortable truth: one outage can break auth, writes, and customer trust at the same time. That’s why we built FaaS. It’s managed hot-standby failover for Supabase: a dedicated standby, automatic reroute when the primary goes down, and write-back sync when it recovers. No code changes. No DNS cutover. No rebuilding your app around a different stack. I’m not trying to sell “more infrastructure.” I’m trying to sell less incident pain. If you’re a founder, CTO, or engineer running production on Supabase, the question is simple: what happens to your business the first time the backend you rely on has a bad hour? FaaS exists so the answer is not “we lost the day.”
Angle: missing HA layer for Supabase
Supabase is a strong default. But for production apps, a default is not a disaster recovery plan. Most teams discover this too late. They ship on Supabase, get product-market fit, and then realize they now own the awkward part: failover, recovery, and keeping clients alive when the primary has a bad day. FaaS is the missing HA layer. It sits in front of your Supabase project, keeps a hot standby ready, reroutes traffic automatically, and syncs writes back after recovery. What we are optimizing for: - no app rewrite - no custom router - no manual incident playbook at 2 a.m. I built this because I think infrastructure should disappear until it is needed. Then it should just work.
Angle: why not build your own failover stack
You can build failover yourself. You can also build your own auth, payments, and analytics pipeline. The real question is: should you? For a Supabase app, proper failover usually means Cloudflare, replication, health checks, edge routing, recovery logic, and a bunch of messy edge cases around auth and writes. FaaS packages that into a managed layer. The goal is not to be clever. The goal is to keep your app usable during an outage and then reconcile changes cleanly after recovery. If you’re a small team, that matters. Because the cheapest outage is the one your customers never notice. I’d rather spend time shipping product than pretending I want to be on-call for routing logic.

Hot-standby failover for Supabase
Description
Keep your Supabase app up during outages with automatic failover, edge routing, and write-back sync. No code changes, no DNS cutover, and no manual recovery runbook.
Maker's first comment
I built FaaS after watching the same pattern repeat: teams ship on Supabase, everything feels great, and then the first real outage turns into a fire drill. Suddenly auth is flaky, writes are failing, customers are asking what happened, and the team is stuck explaining infrastructure instead of fixing it. FaaS is my attempt to remove that pain. It provisions a hot standby for Supabase, keeps it synced, reroutes traffic automatically when the primary goes down, and replays writes back after recovery. The goal is simple: your app stays usable while your primary recovers. I know this is a skeptical category, so I’m not asking people to trust marketing. I’m asking them to look at the failover path, test it, break it, and tell me where it fails in the real world. That feedback is the whole reason I launched this now.
Pinned maker comment
I’d love feedback on the failover semantics, especially auth, subscriptions, and write-back recovery. If you run Supabase in production, what edge cases would make you say “nope”?
