Cost to build an app like Facebook
A Facebook-like app is defined by breadth. Profiles, a ranked feed, groups, events, a marketplace and messaging are six distinct products sharing one identity system. Nobody builds all of it at once, and an estimate that includes everything is really an estimate for a multi-year programme rather than a project.
What you are actually building
An app like Facebook is three or four screens people recognise sitting on a great deal of engineering they never see. These are the screens that define the shape — and the part of each one that costs real money.
The feed
Fan-out, pagination, caching and read state. A feed still fast past a few thousand follows is a backend problem, not a UI one.
Media upload
Client-side compression, resumable uploads, transcode, thumbnails and a CDN. The upload path fails in more ways than any other screen.
Moderation
Reporting, review queues, automated classification and appeals. Not optional the moment strangers can post to each other.

What makes a Facebook-like app expensive
Three things dominate this shape of product. Everything else is comparatively ordinary app development.
Surface area
Every additional module multiplies not just build hours but permissions, notifications, search and moderation work across all of them.
Groups and permissions
Public, private and hidden spaces with roles, invitations, moderation and separate feeds inside each.
Notification volume
Dozens of notification types with per-user preferences and digesting, or users disable notifications entirely and never come back.

How long, and who builds it
The $693,000–$1,134,000 figure assumes this schedule and this team. Both scale with the answers in the calculator above — and neither is a quote.
Delivery timeline — 9–13 months
- Discovery & product definition4–6 wks
- UI/UX design6–9 wks
- Development (app + backend)21–29 wks
- Integrations & infrastructure6–8 wks
- QA & security testing6–8 wks
- Store submission & launch2–3 wks
The team — 7 people

- DevOps / SRE1×½
- QA engineer1×
- Data / ML engineer1×
The phases add to more than the total on purpose: design starts before discovery finishes and QA runs alongside development rather than after it. 7 people is about 6.5 full-time equivalents — a smaller team takes proportionally longer, and a much larger one does not go proportionally faster. The two roles most often missing from a first plan are DevOps and QA, which together are 15% of this build.
Technology considerations
A stack that would serve this product shape well. A recommendation for what you could build — not a claim about what Facebook runs.
| Layer | Suggestion |
|---|---|
| Mobile | Native iOS and Android — camera, media handling and scroll performance decide retention |
| Backend | Go or Node.js services with a dedicated feed-generation service |
| Database | PostgreSQL for accounts, Cassandra or DynamoDB for the timeline and social graph |
| Cache | Redis for feed pages, counters and sessions |
| Search | OpenSearch for people, hashtags and places |
| Real-time | WebSocket for messaging and live presence |
| Cloud | AWS |
| Object storage | S3 for original and derived media |
| CDN | CloudFront with on-the-fly image transforms |
| Media pipeline | Image and short-video processing pipeline with automatic moderation screening |
| Monitoring | Datadog with feed-latency and moderation-queue dashboards |
| ML serving | A managed inference endpoint (SageMaker, Vertex AI) with an offline evaluation pipeline |
Top cost drivers
- 1
Medium scale traffic and usage19% of the build
Caching, queues and real monitoring become mandatory. That is real engineering: caching layer (redis or equivalent) in front of hot reads; background job queue for anything slower than a request; read replicas and query-level database tuning. Lower your year-one traffic assumptions and this shrinks immediately.
- 2
Advanced backend architecture9% of the build
Needed when traffic is high enough, or spiky enough, that a single service cannot absorb it and a slow endpoint takes the whole product down with it.
- 3
iOS + Android, native5% of the build
Two separate native codebases means the client is built twice. Moving to React Native or Flutter would cut roughly a third of your mobile hours, at the cost of native modules wherever you touch device hardware.
- 4
5 third-party integrations4% of the build
Every external service is code you write, failure modes you handle and an API that will change without asking you. The ones you can defer are the cheapest scope cuts available.
- 5
Premium design3% of the build
Roughly 27 screens with research, motion and accessibility work. Dropping to Custom would save a meaningful share of this without making the product look unfinished.
- 6
COPPA compliance work2% of the build
Engineering and evidence work to make an audit survivable. Certification fees, legal review and auditor time are separate costs that this estimate excludes.
Infrastructure and maintenance
Neither of these is part of the build figure, and neither of them stops.
Cloud infrastructure
$2K – $11K/month
- Baseline environment$120–$420
- Application compute$675–$2,400
- Database$27–$108
- Object storage$105–$130
- CDN & bandwidth$36–$82
- Media transcoding$25–$67
Annual maintenance
$104K – $284K/year
15–25% of build cost per year: bug fixes, iOS and Android version updates, SDK and dependency upgrades, security patching and small improvements. Cloud costs are the separate figure alongside.
Building an app like Facebook — common questions
How much does it cost to build an app like Facebook?
Using this site's default profile — 18 features, ios + android, native, a advanced backend and medium scale traffic — the estimate is $693,000 to $1,134,000 for a US team, or roughly 6,530 engineering hours at a blended $118–$155 per hour. That figure covers design, both apps, backend, infrastructure, integrations, security, QA, DevOps and project management. It excludes cloud hosting, vendor fees, marketing and legal. Change any answer in the calculator on this page and the number moves with it.
How long does it take to build an app like Facebook?
About 9–13 months with the team this estimate assumes — 7 people, roughly 6.5 full-time equivalents. Discovery and design run first and partly in parallel, development takes about half the calendar, and QA overlaps the back half rather than following it. A smaller team takes proportionally longer; a much larger one does not go proportionally faster, which is why compressing this schedule costs more than it saves below a certain point.
What team do you need to build an app like Facebook?
1× product manager, 1× ui/ux designer, 1× mobile developer, 1× backend developer, 1× devops / sre (part-time), 1× qa engineer, 1× data / ml engineer. That is what 6,530 hours of work distributed across 10 disciplines actually requires. The roles people most often leave out of their own plan are DevOps and QA, which together are about 15% of this build.
What does an app like Facebook cost to run each month?
Cloud infrastructure is estimated at $1,528 to $11,057 per month at the scale this profile assumes, driven mainly by media delivery and transcoding. Third-party services add $380 to $7,500. Separately, budget $104,000 to $284,000 a year for maintenance — bug fixes, OS and SDK updates and security patching. None of these are part of the build figure.
Is a general social network realistic for a startup?
Only if it is narrow. Successful new social products launch around one behaviour for one community, then widen. A broad clone competes on network effects, which cannot be bought with engineering hours.
How much does adding groups cost?
Groups with roles, moderation and their own feeds add roughly 120–200 hours, plus a permission model that touches every other feature you have already built.
