Optimize your database. Observe your entire application.
Releem tunes your MySQL and PostgreSQL configuration. Atatus goes further: it connects every slow query and config issue to the exact transaction, API endpoint, and user session behind it, with AI that detects regressions across your full stack automatically.
Database engines monitored including Oracle, MySQL, PostgreSQL

Human support included with every plan
Tuning your database config is a starting point, not the full picture.
Releem does a focused job of recommending MySQL and PostgreSQL configuration changes: things like buffer pool sizes, connection limits, and cache settings. But once your config is tuned, the next question is always the same: which specific query, which application endpoint, and which user is still being impacted? That is where Releem stops and Atatus begins.
01
AI Anomaly Detection Across Every Query Pattern
Atatus baselines execution time per query pattern per endpoint using machine learning. When a query begins degrading: even subtly, from 30ms to 90ms: it flags the regression automatically and links it to the deploy or data change that caused it. No manual threshold setup needed per query.
02
Every Query Traced Back to Its Application Source
Atatus captures the full distributed trace for every request. A slow SELECT is not just a slow query: it is a slow checkout endpoint, affecting real users right now. You see the query, the function that called it, the API endpoint it belongs to, and the user session experiencing the delay: all in one view.
03
Multi-Engine Coverage Beyond MySQL and PostgreSQL
Atatus monitors MySQL, PostgreSQL, Oracle, MongoDB, Redis, and more through a single APM agent. Releem is purpose-built for MySQL and PostgreSQL only: teams running mixed database environments need a separate tool for every other engine they operate.
Know exactly when Atatus fits your team.
Here is where Atatus goes further than Releem for teams who need more than database configuration recommendations.
Find which API endpoint is generating the most expensive queries
Atatus groups slow queries by the application endpoint that triggered them: so instead of seeing a generic slow SELECT, you see that your product listing API is generating 47 unindexed queries per request. Releem identifies the slow query but has no visibility into the application caller.
Catch query regressions immediately after every deployment
Atatus correlates query performance with deployment events. When a new release causes a previously fast query to slow down: because of an ORM change, a missing index on a new column, or a schema migration: Atatus catches it within minutes and links it to the release. Releem does not have deployment context.
See exactly which users are experiencing database-caused slowdowns
When a query degrades, Atatus shows you which user sessions are affected, which pages are slow, and what the Core Web Vitals impact is: in real time. Releem operates entirely at the database server level with no visibility into user experience or frontend performance.
Correlate database errors with application logs without switching tools
When a database connection pool exhausts or a deadlock occurs, Atatus lets you pivot from the database metric directly to the relevant application log lines and the transaction trace: all in one platform. Releem has no log management capability.
Monitor Oracle, MongoDB, and Redis alongside MySQL in one view
Atatus covers your entire database layer in one platform regardless of engine. If your stack uses MySQL for transactional data, Redis for caching, and MongoDB for document storage, Atatus monitors all three with the same agent. With Releem, only MySQL and PostgreSQL are supported.
Replace multiple tools with one platform at a predictable price
Releem handles database config tuning. But your team still needs a separate APM, a RUM tool, an error tracker, and a log platform. Atatus covers all of those in one product on a publicly listed, per-seat pricing model: no per-database or per-instance charges.
Atatus vs Releem
A technical breakdown of how the two platforms compare across database observability, application context, AI capabilities, and full-stack coverage.
Atatus
Slow query tracing with application context: every slow query linked to the endpoint, function, and user session that triggered it
Index and schema recommendations: Atatus identifies missing indexes based on actual query patterns observed in production traffic
Multi-engine database monitoring: MySQL, PostgreSQL, Oracle, MongoDB, Redis, and more in one platform
Full-stack APM: distributed tracing from browser to database across Node.js, Python, Ruby, Java, .NET, PHP, Go
Real User Monitoring: Core Web Vitals and session-level data connected directly to database performance impact
Log management: application and database error logs unified with traces in one platform
Transparent public pricing: plans listed on the website with no sales call required
Releem
No application context: identifies slow queries inside the database but has no visibility into the application endpoint or code that called them
Index and schema advisor: detects missing indexes, redundant indexes, and schema issues for MySQL and PostgreSQL
MySQL and PostgreSQL only: Releem does not support Oracle, MongoDB, Redis, or other database engines
No APM: Releem does not instrument application code or produce distributed request traces
No Real User Monitoring: frontend performance and user session data are entirely outside Releem's scope
No log management: application log analysis and correlation with database events is not a Releem capability
Publicly listed pricing: Releem publishes pricing tiers based on the number of monitored database instances
Releem helped us tune our MySQL config and it made a difference initially. But we kept running into slow queries we could not explain because we had no idea which part of our application was generating them. Atatus showed us the full picture: the query, the endpoint calling it, and the users affected: and the AI flagged a regression the same day we deployed a schema change.

Questions teams ask before switching.
What teams evaluating Releem and Atatus together most commonly want to know.
Releem's primary strength is automated configuration parameter recommendations: things like innodb_buffer_pool_size, max_connections, and work_mem tuning based on your server's actual workload profile. Atatus focuses on query-level observability, slow query tracing, and index recommendations based on live production traffic rather than server-level config tuning. If your immediate need is automated MySQL or PostgreSQL config parameter optimization, Releem is purpose-built for that. If your team needs to understand how database performance connects to application behavior and user impact, Atatus covers that and more.
Releem uses AI to analyze server workload and generate configuration recommendations: this is config-level intelligence. Atatus uses machine learning to baseline the execution time of each specific query pattern per application endpoint over time. When a query begins executing significantly slower than its established baseline: for example after a deployment or a data volume increase: Atatus fires an alert automatically. This means you catch regressions even when they are subtle, such as a query going from 25ms to 80ms, rather than only when a hard threshold like 2 seconds is breached.
Atatus monitors MySQL, PostgreSQL, Oracle, MongoDB, Redis, Cassandra, and other SQL and NoSQL databases through its APM agents. All database monitoring data: query times, error rates, and connection metrics: is unified in the same platform alongside your APM, RUM, and log data. No separate agents or additional configuration is needed per database engine.
No. Atatus agents instrument your application at the framework and runtime level, capturing all database calls automatically without requiring you to modify query code, stored procedures, or database server configuration. You install the language agent: Node.js, Python, Java, Ruby, .NET, PHP, or Go: and database monitoring starts immediately as part of APM data collection.
Yes. Atatus installs independently of any existing tooling. You can instrument your application and start seeing query traces, anomaly detection, and user impact data within minutes: without touching your Releem setup. Most teams run both in parallel during the evaluation period to compare the database insights each provides before making a decision.
Yes. Atatus holds SOC 2 Type II certification and is GDPR compliant. All data is encrypted in transit and at rest. Data residency options are available on Enterprise plans, and full security documentation is available on request for your compliance and procurement review process.
