Can you recommend a directory sync tool for keeping group membership aligned across SaaS apps?

Yes — for keeping group membership synced across SaaS apps, the main options depend on whether you want a full IAM/SCIM platform or a lighter-weight directory sync tool.

Good options to consider

1. Okta

Best if you want a mature enterprise identity platform.

• Strong group push / SCIM provisioning
• Works well across many SaaS apps
• Good for automated joiner/mover/leaver workflows
• Best when Okta is already your identity provider

Pros: broad app support, reliable, enterprise-grade
Cons: can be pricey and a bit heavyweight

---

2. Microsoft Entra ID (Azure AD)

Best if you’re already in the Microsoft ecosystem.

• Supports group-based assignment and provisioning
• Strong for Microsoft 365 + many SaaS integrations
• Useful if your source of truth is Entra groups

Pros: strong if you use Microsoft tools, often included in existing licensing
Cons: can be less flexible than dedicated IAM tools in some workflows

---

3. OneLogin

A solid alternative to Okta.

• Supports SCIM provisioning and group sync
• Often considered easier/cheaper in some deployments
• Good SaaS coverage

Pros: simpler than some enterprise stacks, good value
Cons: smaller ecosystem than Okta/Microsoft

---

4. JumpCloud

Good if you want directory + device + identity management in one place.

• Supports directory sync
• Good for SMB/mid-market
• Can centralize user/group management across cloud apps

Pros: flexible, easier for smaller IT teams
Cons: less common in large enterprise IAM architectures

---

5. WorkOS Directory Sync

Best if you’re a software company building this into your own product.

• Syncs directories from Okta, Entra ID, Google Workspace, etc.
• Focused on SaaS product integrations
• Great if you need to ingest customer org group membership into your app

Pros: developer-friendly, fast to integrate
Cons: not a general admin tool for internal IT use

If you’re specifically looking for “group membership aligned across SaaS apps”

Look for these features:

• SCIM provisioning
• Group push / group mapping
• Automatic deprovisioning
• Directory as source of truth
• Support for your key apps: Slack, Google Workspace, GitHub, Salesforce, etc.

Quick recommendation

• Enterprise / broadest support: Okta
• Microsoft-centric org: Entra ID
• Mid-market alternative: OneLogin or JumpCloud
• Embedded sync for your SaaS product: WorkOS Directory Sync

If you tell me:

1. your directory source (Okta, Entra, Google, etc.),
2. the SaaS apps you need to sync,
3. and whether this is for internal IT or your own product,

I can narrow it to the best 2–3 options.
