Open Source vs. Proprietary SaaS: Technical Governance Benchmark
Evaluating data sovereignty, enterprise security policies, and recurring platform costs across 8 foundational enterprise criteria.
| Evaluation Dimension | GrowthBook (Open Source) | LaunchDarkly (Commercial SaaS) |
|---|---|---|
| Data Sovereignty & Residency | 100% On-premise or private VPC. You own the database and persistent volumes (GDPR & HIPAA compliant). | Multi-tenant US/EU cloud silos. Subject to vendor privacy policy revisions and third-party AI training. |
| Seat Scaling & User Licensing | $0 Software License. Scale 5 to 1,000+ internal users at zero incremental per-seat cost. | $12 / seat / month + MAU overage charges. Invoices scale linearly with team growth. |
| Enterprise SSO & Security Tax | Native OIDC / SAML support or free integration with Keycloak / Authentik without paywall tiers. | Single Sign-On (SAML/Okta) routinely locked behind 2x–4x expensive Enterprise tiers (the “SSO Tax”). |
| API Rate Limits & Automation | Uncapped local RPC & Webhook throughput. Direct SQL access for reporting and internal tooling. | Strict rate-limiting headers, operations/minute caps, and paid API tiers for automated workflows. |
| Offline LAN Operation & Latency | 100% operational on local network or private VPC with sub-millisecond response times. Zero dependency on public internet uplink. | Continuous dependency on public WAN connections and multi-tenant US/EU data centers; vulnerable to cloud outages. |
| Disaster Recovery & Snapshots | Uncapped RPO/RTO control. Automated daily database dumps, volume snapshots (Restic / S3), and instant local rollback. | Point-in-time recovery gated behind expensive Enterprise plans or manual support requests with 24-48h delays. |
| Source Code & Customization | Full source inspection under MIT. Patch security fixes, add custom plugins, or fork freely. | Black-box proprietary codebase. Feature requests depend entirely on vendor corporate roadmap. |
| Exit Barrier & Portability | Standard SQL dumps, JSON/CSV exports, and raw files. Migrate to any cloud provider in minutes. | High switching cost. Data exported in fragmented formats with loss of revision histories. |
Migration Feasibility Assessment: Should You Switch to GrowthBook?
Commercial SaaS tools like LaunchDarkly charge compounding per-user fees that escalate as headcount increases.
Proprietary cloud SaaS stores your records in shared multi-tenant silos subject to corporate policy changes.
Containerized open-source software requires standard Linux VPS provisioning and basic container lifecycle management.
Cloud SaaS imposes strict API rate limits, operations/minute quotas, and locks raw database schemas behind paywalls.
Most commercial vendors enforce an 'SSO Tax', demanding 2x to 4x higher pricing tiers simply to connect corporate identity.
Selective POC Migration: Evaluate Staging Deployment
Your team has clear cost or privacy incentives, but should run a 1-week staging pilot of GrowthBook alongside LaunchDarkly to validate daily operational workflows before executing a complete cutover.
5-Step Migration Blueprint: Moving from LaunchDarkly to GrowthBook
Practical engineering roadmap for transitioning team data from LaunchDarkly to a self-hosted GrowthBook Docker instance.
Data Export
Trigger a full workspace export from LaunchDarkly settings (download ZIP containing raw JSON, CSV, or Markdown assets).
Provision VPS
Deploy an Ubuntu 24.04 LTS instance ($5–$15/mo on Hetzner or DigitalOcean) and install modern Docker with Compose v2.
Run Compose
Copy the verified GrowthBook docker-compose.yml configuration below, customize secrets, and launch with docker compose up -d.
HTTPS & Domain
Bind your custom domain (e.g. growthbook.yourcompany.com) via Caddy or Traefik with automated Let's Encrypt SSL.
Import & Cutover
Import archived datasets into GrowthBook, invite team members, configure automated S3 database backups, and cancel LaunchDarkly.

GrowthBook vs LaunchDarkly: Frequently Asked Questions
What is the primary difference between GrowthBook and LaunchDarkly?
GrowthBook is a self-hosted open-source software (MIT licensed) focused on Open source feature flagging and experimentation platform. In contrast, LaunchDarkly is a commercial cloud service focused on Enterprise feature management and progressive rollout platform.
How much money can a 25-person team save by choosing GrowthBook?
Commercial per-seat SaaS tools typically charge $10–$40/user/month ($3,000–$12,000/year for 25 seats). Self-hosting open-source software on a private VPS (typically $10–$25/month on Hetzner or DigitalOcean) reduces recurring software expenses by up to 95%.
What are the production server hardware requirements for self-hosting?
For GrowthBook, recommended baseline memory is 1 GB - 2 GB RAM (Hetzner CX22 / $4/mo). For LaunchDarkly, recommended memory is Cloud Managed (0 MB Server RAM). Both can be provisioned using modern Docker Compose configurations.
Is data export and migration supported between GrowthBook and LaunchDarkly?
Yes. Open-source solutions prioritize data portability with standard SQL database dumps, JSON/CSV exports, or native markdown files, ensuring zero vendor lock-in.
