Best Reverse ETL Software in 2026: Pricing & Comparison
We compared four reverse ETL platforms on published pricing, free tiers, sync limits, and warehouse activation so data teams can shortlist quickly.
- Limited free start with warehouse activation: Hightouch — free tier with up to 2 active syncs.
- Published Growth pricing with event volume: RudderStack — free plan; Growth from $265/month for 1M events.
- Usage-based under Fivetran: Census (now Fivetran Activations) — free tier available; Activations billed on Monthly Active Rows (MAR); no fixed public Professional list price.
- Published starting rate for bidirectional sync: Polytomic — pricing begins at $500/month for Standard.
Reverse ETL software syncs modeled data from a data warehouse or lake into operational tools such as CRMs, ad platforms, and support systems.
Every platform is evaluated on the same fields: published pricing, free plan or trial, core focus, and main limitation. Order is not a quality ranking. We sorted public $0 / published price first and quote-led last.

The 4 companies in detail
Hightouch
Best for limited free start
Best for: teams that want to test reverse ETL with a free tier limited to a small number of active syncs before moving to usage-based or quote plans.
| Published pricing | Free tier with up to 2 active syncs; higher self-serve and Business plans are usage-based or quote |
|---|---|
| Free plan or trial | Free plan for limited active syncs |
| Core focus | Reverse ETL from warehouses to 200+ destinations with audience and activation features |
| Main limitation | Most production volume and advanced features require sales contact or usage pricing |
- Official materials show a free entry limited by active syncs.
- Broad destination coverage for marketing and operational tools.
- Clear dollar rates for higher tiers are not fully published; most buyers talk to sales.
RudderStack
Best for published Growth pricing
Best for: engineering teams that want a free event-volume tier and a published Growth starting price for reverse ETL plus event streaming.
| Published pricing | Free (250K events/month); Growth from $265/month for 1M events (annual discount available); Enterprise quote |
|---|---|
| Free plan or trial | Free forever plan; 30-day trial on Growth |
| Core focus | Event collection, transformations, warehouse sync, and reverse ETL connections |
| Main limitation | Faster syncs, unlimited connections, and advanced identity features sit on Enterprise |
- Official pricing page publishes Free and Growth dollar rates with event limits.
- Reverse ETL connection counts scale by plan (10 on Free, 25 on Growth).
- Enterprise security, HIPAA, and lowest-latency syncs require a quote.
Census
Best for Fivetran-integrated activation
Best for: teams already on or evaluating Fivetran who want warehouse-to-tool activation under the same usage-based contract.
| Published pricing | Free tier available; Activations billed on Monthly Active Rows (MAR) under Fivetran usage-based pricing; no fixed public list price for Professional |
|---|---|
| Free plan or trial | Free plan with limited destinations and syncs |
| Core focus | Warehouse-to-tool activation with dbt integration and audience features on higher tiers |
| Main limitation | Post-acquisition packaging under Fivetran means buyers should verify the current list price on the live page |
- Free tier exists; current billing is usage-based MAR under the Fivetran platform (post-acquisition).
- Strong dbt and warehouse-native modeling for data teams.
- Enterprise connectors, continuous sync, and Audience Hub are quote or higher-tier items.
Polytomic
Best for bidirectional operational syncs
Best for: teams that need reverse ETL plus bidirectional syncs between operational systems and the warehouse under a published starting rate.
| Published pricing | Pricing begins at $500/month for Standard; Enterprise quote |
|---|---|
| Free plan or trial | No permanent free plan listed; sales conversation for plans |
| Core focus | Bidirectional data sync covering reverse ETL, CDC, and app-to-app connections |
| Main limitation | No free self-serve tier; Standard and above require contacting sales even though a starting rate is published |
- Official pricing page states pricing begins at $500/month.
- Supports sync in both directions, useful for operational data flowing back to the warehouse.
- Detailed plan limits and self-serve signup are not fully public; most buyers book a call.

I want a free start with a couple of syncs
I need published dollar rates I can budget
I need bidirectional operational syncs
Buying tip
Ask whether pricing is based on active syncs, event volume, rows, or destinations. The same “starting at” number can scale very differently once volume grows.
How this comparison was put together
We checked official pricing and product pages on 18 October 2026. Where a page redirected or showed only a starting rate, we recorded exactly that. Pricing cells distinguish free plans, published list rates, and quote-led tiers. Order follows public $0 or lowest published starting price first. No vendor paid for placement.
What is reverse ETL?
Do these tools require an existing warehouse?
Yes. Reverse ETL assumes you already have a warehouse or lake as the source of truth. Event collection and warehouse loading are separate steps.
Why do some pages show only a starting price?
Many reverse ETL vendors publish a free or entry rate and move higher volume, security, and audience features to usage pricing or sales quotes.
