Modulis vs Sherlocks.ai: BYOC Managed Production Resolution — Full 2026 Comparison

Quick answer

Sherlocks.ai is a Slack- and Microsoft Teams-native AI SRE product: 16+ specialized AI agents investigate incidents, correlate telemetry and recent changes, and return an evidence-backed root cause analysis inside chat, using a read-only “Watson” agent that reads your infrastructure directly. It’s an investigation layer on top of your existing infrastructure and observability tools, not a telemetry platform in its own right. Modulis is the underlying platform: it collects and correlates logs, traces, metrics, errors, and session data itself, deployed inside your own cloud from day one, and adds AI-assisted root cause analysis and PR-ready fixes on top of that first-party data.

Who each is for

Sherlocks.ai fits teams that want a fast, chat-native way to get AI-driven incident investigation without replacing their existing observability stack — its free tier (30 investigations/month) makes it easy to try. Modulis fits teams that want to consolidate observability, session replay, product analytics, and AI-assisted resolution into one platform, with BYOC data ownership as the default rather than an enterprise-tier upgrade.

Architecture and data ownership

This is the clearest difference between the two. Modulis is BYOC at every tier, including Free — your telemetry and AI inference both stay inside your own cloud account from the start. Sherlocks.ai’s free and standard experience is SaaS; in-VPC LLM processing and air-gapped deployment are only available on its custom-priced Enterprise plan, alongside SSO/SAML, audit logs, and a dedicated field engineer for setup. If BYOC data residency needs to be the default rather than an Enterprise add-on, that’s a material difference.

AI capabilities

Both platforms lead with AI-driven root cause investigation. Sherlocks.ai’s 16+ agents correlate logs, metrics, and traces across your existing infrastructure and produce an evidence-backed RCA in Slack, with read-only access to reduce risk. Modulis’s AI-assisted resolution runs across its own correlated telemetry — including session replay and Git metadata — and can produce PR-ready code fixes, running on your own model key (BYOK) inside your cloud boundary.

Pricing approach

Sherlocks.ai’s Free plan is genuinely free (30 investigations/month, all agents included), with Enterprise moving to custom pricing for unlimited investigations and the compliance features above. Modulis publishes flat, tier-based subscription pricing from $0, with unlimited data ingestion on every paid tier — see the Pricing page for details.

When to choose Modulis

Choose Modulis if you want BYOC data residency by default (not an Enterprise-tier upgrade), plus the underlying observability, session replay, and product analytics platform itself — not just an investigation layer sitting on top of tools you’re already paying for separately.

When Sherlocks.ai may be a better fit

If you already have observability tooling in place and want a low-friction, chat-native AI SRE layer to speed up investigation — and a SaaS deployment model is acceptable for your compliance requirements — Sherlocks.ai’s free tier is a fast way to evaluate that specific workflow.
