Middleware, as an observability platform, is designed to provide developers and SRE teams with visibility into distributed systems by aggregating metrics, logs, traces, and events into a unified monitoring experience. Its clean UI, eBPF-powered insights, and fast onboarding have made it popular among DevOps teams.

However, while Middleware offers strong features for observability pillars, many users have experienced integration issues, a learning curve, and configuration complexity. The platform offers SaaS-based free and paid tiers, while BYOD is allowed only in the Enterprise tier. So, users, especially in highly regulated industries, need to validate data residency concerns carefully.

This is where CubeAPM emerges as the best Middleware alternative. CubeAPM delivers high-performance observability with self-hosted deployment for data localisation, better cost-efficiency ($0.15/GB), and seamless 800+ integrations. This article explores the 7 best Middleware alternatives based on OpenTelemetry support, MELT coverage, self-hosting options, and more.

Why People Are Looking for Middleware Alternatives

Cost Complexity & Scaling Difficulty

While Middleware advertises itself as an affordable and lightweight observability solution, many teams find that its pricing model becomes unsustainable as telemetry volume increases. Middleware offers three pricing tiers:

• Free: up to 100GB of data ingested, up to 1k RUM sessions, and up to 20k synthetic checks
• Pay-as-you-go: $0.30/GB for additional metrics, logs, and traces
• Custom: Enterprise solutions.

Although the pricing looks straightforward, scaling can be challenging. In environments with many microservices, containers, or heavy tracing/logging, the ingest volume (and thus cost) can escalate quickly. Unless ingestion controls are diligently used, what begins as “lightweight and cost-effective” monitoring can become expensive.

Limited Self-Hosting

Middleware’s free and pay-as-you-go pricing tiers are cloud-only. Only the custom pricing tier, suitable for enterprises to meet their specific needs, has on-premise or BYOD. This means, unless you choose the custom pricing, you can’t host your data on your cloud infrastructure. This could be a problem for small and medium-sized businesses with budget constraints or for those with strict data privacy requirements.

Tools, such as CubeAPM, offer on-premise/BYOD options where data is stored inside the customer’s own environment, ensuring compliance with regional regulations, minimising egress costs, and eliminating data control concerns.

Integration Issues

Many users report that Middleware’s integrations, especially with lesser-known tools or cloud providers, may require manual setup and custom workarounds, which adds to the effort and time before everything works smoothly. Because of this, teams sometimes face unexpected configuration complexity, undermining Middleware’s promise of “out-of-the-box” convenience and reducing productivity during integration-heavy workflows.

Criteria for Selecting Middleware Alternatives

1. Native OpenTelemetry (OTEL) Support

A modern observability platform should support OpenTelemetry natively—not just for traces, but for logs, metrics, and events. OTEL-native tools simplify instrumentation, enable vendor-neutral telemetry collection, and avoid lock-in. This ensures compatibility across cloud, container, and edge environments.

2. Full MELT Stack Coverage

Look for platforms that provide comprehensive MELT support—Metrics, Events, Logs, and Traces—in a unified view. This eliminates the need for piecemeal tooling and enables true end-to-end observability across services, infrastructure, and user experience. Tools with partial coverage (e.g., just logs and traces) fall short in complex environments.

3. Self-Hosting and Data Localization Compliance

Self-hosted or hybrid deployment options are crucial for organizations operating in regulated industries or under data residency laws (e.g., GDPR, HIPAA, RBI). Alternatives should allow teams to run the platform in their own cloud or on-prem infrastructure, ensuring full control over data flow, retention, and encryption.

4. Transparent, Scalable Pricing Models

Avoid tools that are priced based on ingest volume or number of users, as these models scale poorly in microservice-heavy architectures. Prefer infra-based or sampling-optimized pricing that remains predictable even with high data volumes. Transparency also means no hidden charges for features like longer retention or synthetics.

5. Sampling Support

Effective sampling reduces cost while retaining high-value telemetry (e.g., outliers, errors, latency spikes). Tools with intelligent or tail-based sampling preserve insights from edge cases and debug-worthy events, whereas naive probabilistic sampling risks missing critical signals in production.

6. Synthetic Monitoring and Real User Monitoring (RUM)

Alternatives should include built-in synthetic monitoring for uptime checks and latency benchmarking, and RUM for understanding frontend performance from the user’s perspective. These capabilities are essential for catching issues before users do and ensuring SLAs from end to end.

7. DevOps and Ecosystem Integration

Look for tools that integrate smoothly with CI/CD pipelines, alerting systems (Slack, PagerDuty), SLO dashboards, and cloud-native services. Tight integration ensures faster incident response, better automation, and operational consistency across environments.

8. Support Quality and Developer Experience

Fast, reliable support—preferably via Slack or chat with real engineers—is a must during incidents or onboarding. Tools with slow ticketing systems or limited documentation can stall development. An intuitive UI, strong documentation, and fast query performance all contribute to developer productivity.

New Relic vs Middleware

New Relic provides granular telemetry exploration using NRQL, anomaly detection, customizable dashboards, and strong support for OpenTelemetry and Prometheus pipelines. Middleware, while easier to deploy, does not yet offer equivalent telemetry flexibility or advanced querying capabilities.

Both tools offer RUM and synthetics, but New Relic’s UX is far more customizable, and it provides broader integrations into CI/CD pipelines and cloud-native tools. Middleware’s current query and visualization stack are better suited for basic to intermediate monitoring needs, whereas New Relic excels in power-user observability workflows.

Pricing & Customer Reviews

• Log Ingestion: Starts at $2.50/GB/day
• RUM, metrics, and tracing: Available via advanced plans or add-ons
• Pricing is consumption-based (daily ingest + scan volume), which can spike under heavy load

• G2 Rating: 4.3/5 (600+ reviews)
• Praised for: Scalability in log management, strong SIEM capabilities, and ease of integration
• Criticized for: High and unpredictable costs, limited OTEL support, and sluggish performance with complex dashboards

Sumo Logic vs Middleware

Sumo Logic leads in log analytics, security observability, and compliance dashboards. Middleware’s log and trace capabilities are strong, but it lacks features like LogReduce™, SIEM integration, and advanced alert correlation. Sumo Logic also has deeper multi-cloud integrations and built-in compliance support (PCI, HIPAA, SOC2), which Middleware doesn’t match.

While Middleware supports RUM and synthetics, its visualization and customization remain limited compared to Sumo Logic’s PowerQuery engine, outlier detection, and prebuilt monitoring packages.

Conclusion: Choosing the Right Middleware Alternative

Middleware offers a clean UI and supports RUM, synthetics, and OpenTelemetry ingestion, but has issues, such as configuration and customization difficulties, and self-hosting limitations.

CubeAPM delivers the most complete and cost-efficient option with native support for OpenTelemetry, full MELT observability, context-aware smart sampling, and real-time drill-down capabilities that unify traces with logs, infra metrics, and user experience data.
