Sematext sells you four separate products - Monitoring, Logs, Experience, and Synthetics each billed independently. Atatus gives you all of this unified in a single platform, under a single predictable bill.
Sematext is a strong observability platform, but Atatus competes where it matters most for fast-growing teams. Sematext offers solid coverage across observability categories and genuinely competitive pricing for its modules individually. The challenge starts when teams need everything together. Its architecture is modular by design such as Monitoring, Logs, Experience, and Synthetics are four separate products, each with its own app-level billing, plan tiers, and retention settings. That structure creates friction at scale. Teams end up paying for multiple Sematext products, managing per-app configurations across separate dashboards, and still relying on workarounds for deeper distributed tracing and true correlated analysis across the stack.
Sematext's modular pricing is flexible but complex. Each App gets its own plan, retention, and billing. Teams end up optimizing four separate cost centers instead of focusing on engineering. Atatus rolls everything into a single per-host rate - APM, logs, RUM, infra, and synthetics included.
Sematext charges $0.10/GB on receive, then up to $1.90/GB for stored data on Pro, meaning log-heavy teams see costs multiply well beyond initial estimates. Atatus includes log ingestion and storage in the flat per-host price, with no per-GB penalties as your log volume grows.
Sematext offers partial OpenTelemetry compatibility but does not support full native OTel pipelines. Teams standardizing on OTel for vendor-neutral instrumentation find Sematext requires proprietary agent configurations. Atatus supports OpenTelemetry-native ingestion alongside its own agents.
Here's the specific profile of Sematext users who find the most value switching to Atatus and where Sematext still wins.
If your team runs Sematext Monitoring, Logs, Experience, and Synthetics simultaneously, you're managing four separate billing relationships. Atatus replaces all four under a single per-host flat rate - simpler budgeting, no cross-product data transfer costs, and no surprise overage from one module affecting others.
If you're regularly investigating issues that surface days after they occur - intermittent database errors, gradual memory leaks, seasonal traffic regressions. Sematext's 7-day default isn't enough. Atatus provides 90-day retention on all paid plans, letting your team look further back without paying for retention upgrades.
Sematext's transaction tracing gives you service-level visibility but stops short of method-level profiling. Atatus APM surfaces the specific functions, database queries, and external calls responsible for slowdowns with flamegraph-style traces that developers can act on immediately, not just service maps.
In Sematext, correlating a slow API trace with the exact log lines and host CPU spike at that moment requires switching between apps. Atatus presents APM trace, correlated logs, and infrastructure context in a single unified timeline, reducing the average time to root cause by eliminating cross-app context switching.
If your application generates high log volume including microservices, verbose frameworks, or event-driven architectures. Sematext's per-GB storage costs compound fast. Atatus includes log management in the per-host price with no per-GB billing, so verbose logging events or traffic spikes don't generate unexpected invoices.
Sematext doesn't offer built-in error tracking, teams using it typically add a separate tool like Sentry for exception monitoring. Atatus includes real-time error tracking with stack traces, affected user counts, and release tagging integrated into the same dashboard as your APM and logs with no additional tool needed.
Sematext splits observability across four separate products. Here's how Atatus covers every one of those categories; unified, correlated, and under a single flat price.
Logs fully included in flat per-host price no per-GB ingestion or storage charges
Structured (JSON), unstructured, and semi-structured log formats supported automatically
Full-text search with field-level filters and instant query results
Structured log parsing and custom field extraction out of the box
Live tail view for real-time log streaming during active incidents
Log pattern detection and anomaly alerts surface unusual spikes automatically
One-click trace-to-log correlation jump from a slow APM trace to its exact log context
Infrastructure metadata auto-attached to every log line filter by host, container, or service
Elasticsearch and OpenSearch-compatible API ship logs from any source
Logs Pipelines to filter, transform, and drop noisy events before storage
Billed as a separate product independent pricing, plan, and billing from Monitoring
Storage costs up to $1.90/GB on Pro log-heavy teams see compounding bills
Correlating logs with traces requires switching to the Monitoring app manually
“Marcus was on-call when his company’s checkout API started timing out. He had to jump between monitoring and logs, manually copying trace IDs, and still couldn’t find the root cause quickly. After switching to Atatus, everything was in one place - traces, logs, and infrastructure metrics linked automatically. No tab-hopping. Root cause found in minutes.”
Honest answers to what comes up on every evaluation call with teams currently using Sematext.
Both platforms cover APM, infrastructure, log management, RUM, and synthetic monitoring. The fundamental difference is architecture and billing model. Sematext is modular, each product (Monitoring, Logs, Experience, Synthetics) is a separate App with independent billing, retention settings, and plan tiers. Atatus is a unified platform where all signal types live in a single product under flat per-host pricing. For teams who use all four Sematext modules, Atatus typically simplifies billing and provides tighter cross-signal correlation. Sematext's advantage is its Elasticsearch-compatible log API and strong 100+ integration library, which appeals to teams already operating Elastic-compatible toolchains.
Sematext's default retention across most plans is 7 days. Retention can be extended per App for an additional fee, and Pro plans for Monitoring offer up to 365 days but each extension is paid separately per App. Atatus provides 90 days of data retention on all paid plans with no additional cost. For teams debugging issues that surface days after occurrence, or needing longer windows for compliance and trend analysis, Atatus's default 90-day retention eliminates the need to actively manage and pay for retention upgrades across multiple Sematext apps.
Sematext Logs charges $0.10/GB on receive (regardless of plan), plus storage costs that range from roughly $1.56/GB (Standard) to $1.90/GB (Pro) for stored data. For teams shipping 10 GB/day, storage costs alone can reach $300–$570/month before the base plan price. Atatus includes log ingestion and storage in the per-host flat price there is no separate per-GB billing for logs. Teams with high log volume see the greatest savings when switching, as Sematext's per-GB storage model doesn't favor log-intensive workloads.
Atatus supports OpenTelemetry-native ingestion alongside its own proprietary agents. Teams already instrumented with OTel SDKs can point their OTel collector to Atatus without re-instrumenting application code. Sematext offers partial OTel support but does not provide full native OTel pipeline compatibility; teams relying on standard OTel collectors and exporters may encounter configuration gaps. If your team is standardizing on OpenTelemetry for vendor-neutral instrumentation, Atatus's OTel support is more complete.
Sematext's Elasticsearch and OpenSearch-compatible APIs are a genuine strength, many teams ship logs using ES-compatible clients without needing to reconfigure anything. Atatus uses its own log ingestion API and agents. If your team has built custom log shippers relying on the ES API format, migration will require reconfiguring those shippers to use Atatus's agent or API. For most teams shipping logs via standard integrations (Fluentd, Logstash, Docker logging drivers), the migration is straightforward. Our onboarding team reviews your existing log pipeline and helps configure Atatus's ingestion accordingly.
Yes. Atatus includes real-time error tracking with full stack traces, affected user counts, error frequency trending, and release/deployment correlation. Sematext does not offer built-in error tracking, teams using Sematext for monitoring typically add Sentry or a similar standalone tool for exception management. Switching to Atatus lets teams consolidate error tracking alongside APM, logs, and infrastructure, reducing the number of tools in the observability stack.
Most teams complete migration in 1–3 days. The typical process is: install Atatus agents (replacing Sematext agents on each host), configure log shippers to point to Atatus, set up RUM tags on your frontend, and reconfigure alert notifications. If you're using Sematext's ES-compatible log API with custom shippers, there's an additional reconfiguration step. Atatus provides a dedicated onboarding session with our engineering team to walk through your Sematext setup and configure Atatus equivalents. For Business plans and above, you get a named technical contact throughout the process. Migration support is included at no extra cost.
