Top Recommended Replacements
RudderStack
FREEBest Direct Replacement
Why we like it
Warehouse-native architecture (data stays in your DB); 1:1 API compatibility with Segment (switch by changing one line of code); free tier includes 1M events/mo; enterprise plans are typically 50% cheaper than Segment for high-volume teams.
Keep in mind
Lacks some of the 'no-code' audience building features found in Segment's higher-tier 'Engage' product.
Jitsu (Open Source)
FREEBest for Privacy & Cost
Why we like it
Fully open-source; allows for unlimited data collection if self-hosted; specifically built for high-performance data streaming into ClickHouse, BigQuery, and Postgres; incredible 'Retroactive' data sync features.
Keep in mind
Smaller library of cloud-destination integrations compared to Segment's 750+.
Snowplow Analytics
FREEBest for Data Science
Why we like it
The gold standard for 'Behavioral Data'; gives you absolute control over the data schema; data is delivered in real-time to your warehouse in a highly structured format; no per-user 'tax'.
Keep in mind
Requires a dedicated data engineer to set up and maintain; not a 'plug-and-play' marketing tool.
Hightouch
FREEBest for Reverse ETL
Why we like it
Instead of a CDP, use your Warehouse as the source of truth; Hightouch syncs data *from* your DB to your marketing tools; eliminates the need for Segment entirely if your data is already in a warehouse.
Keep in mind
Requires you to have a mature data warehouse (Snowflake/BigQuery) already established.
PostHog
FREEBest All-in-One for Product
Why we like it
Combines CDP features with Product Analytics, Session Replay, and Feature Flags; free for the first 1M events every month; much more valuable 'all-in-one' suite for startups than Segment.
Keep in mind
The CDP functionality is a secondary feature; fewer third-party integrations than Segment.
Freshpaint
Best for Healthcare (HIPAA)
Why we like it
Specializes in HIPAA-compliant data routing; automatically masks PII (Personally Identifiable Information) before it reaches non-compliant tools like Facebook or Google Ads.
Keep in mind
Pricing is enterprise-focused and not transparent.
June.so
FREEBest for B2B SaaS
Why we like it
Builds your CDP and Analytics on top of Segment or RudderStack; provides 'Company-level' analytics out of the box; very focused on B2B metrics like 'Active Companies' rather than just 'Users'.
Keep in mind
Often works *with* a CDP rather than replacing the infrastructure entirely.
Heap
FREEBest for Autocapture
Why we like it
Captures *every* click and scroll automatically; you don't have to define events upfront; if you forget to track something, you can 'backfill' the data from the past.
Keep in mind
Pricing scales very aggressively; data can be noisy because it captures everything.
MetaRouter
Best for Server-Side Speed
Why we like it
Focuses entirely on server-side tracking to bypass ad-blockers and improve website speed; much lower latency than Segment's client-side library.
Keep in mind
High technical barrier; purely enterprise pricing.
Amplitude (CDP)
FREEBest for Analytics Integration
Why we like it
If you already use Amplitude for analytics, their built-in CDP is 'free' to start; unifies your tracking and analysis in one platform.
Keep in mind
Newer entry into the CDP space; fewer destinations than Segment.
n8n (Self-Hosted)
FREEBest for Custom Workflows
Why we like it
Not a CDP, but an automation tool; you can use it to build your own custom data pipelines between APIs for $0; extreme flexibility for technical founders.
Keep in mind
Requires manual building of every 'sync' logic; no built-in identity resolution.
