Your cloud, your model. Your data never leaves either.

The entire platform, databases included, deploys inside your own cloud account. AI resolution runs on your own LLM key. We operate it; you own the data.

Architecture: inside your cloud account (AWS, GCP or Azure), your apps with the Modulis SDK and OTel send data to the Modulis platform, which uses your own LLM (OpenAI, Anthropic, Bedrock or Azure). Modulis itself only receives health and metadata.

Small or HA, your choice.

A single Docker server for small teams, or a high-availability Kubernetes (EKS) setup for scale. Typical cloud cost: $50–200 a month.

Bring your own key.

AI resolution runs on your OpenAI, Anthropic, Bedrock or Azure OpenAI key. Code and telemetry never reach a model we control.

Built for security reviews.

Data residency by design. Your network, your IAM, your encryption keys, your audit trail.

Modulis vs. typical SaaS observability

Feature	Modulis (BYOC + BYOK)	Typical SaaS stack
Where your data lives	Your own cloud account	Vendor's cloud
AI model	Your own LLM key	Vendor's model and terms
Pricing	Flat per application	Per GB, per host or per seat
Bill when traffic doubles	Same	Roughly doubles
Tools to buy	One platform	APM, errors, replay, analytics
Correlation	Automatic, every signal	By hand, across tools
What you get at the end	Root cause and a pull request	Dashboards and alerts
Setup	Merge one PR	Separate SDK docs per tool

No training on your data, ever
Runs under your IAM, network and encryption policies
SSO, SAML, SCIM and RBAC on Enterprise
Air-gapped and multi-region options
Custom DPA for regulated teams
Built on open OpenTelemetry, no lock-in

Set up by merging one pull request

No docs to read, no instrumentation steps. Modulis opens a PR that adds the SDK to your frontend and backend. Merge, deploy, done.

1
Connect your cloud and GitHub.
Pick AWS, GCP or Azure. Modulis deploys itself into your account.
2
Merge the setup PR.
SDK and config for your stack, ready to review like any other change.
3
Deploy and watch data flow.
Logs, traces, metrics, errors and sessions show up as connected. Usually in under 30 minutes.

One bill that doesn't grow with your traffic

Most teams pay for error tracking, APM, session replay and product analytics separately, and every one of them charges more as data grows. Modulis replaces all four with one flat price per application.

Frequently asked questions

What is Modulis?

Modulis is a production resolution platform that runs in your own cloud. It correlates logs, traces, metrics, errors, session replays and Git metadata, then uses your own AI model to find the root cause and open a pull request with the fix.

What does BYOC and BYOK mean?

BYOC (bring your own cloud) means the whole platform, including its databases, runs in your AWS, GCP or Azure account. BYOK (bring your own key) means AI resolution uses your own OpenAI, Anthropic, Bedrock or Azure OpenAI key. Your telemetry and code never leave your environment.

What data does Modulis receive?

Only platform health and metadata, so we can monitor and upgrade your deployment. Logs, traces, sessions and source code stay in your cloud.

Do I need Kubernetes expertise?

No. Small teams can run Modulis on a single Docker server. Larger teams can choose a high-availability Kubernetes setup. We handle deployment, upgrades and monitoring of the platform either way.

What does it cost to run in my cloud?

Typically $50–200 a month in cloud infrastructure, depending on your traffic and setup. That's paid to your cloud provider, on top of your Modulis plan.

How long does setup take?

Most teams see first data in under 30 minutes. Modulis opens a pull request that adds the SDK; you merge and deploy.

How is Modulis different from Datadog?

Modulis replaces error tracking, APM, session replay and product analytics in one platform, at a flat price per application instead of per-GB ingestion. It runs in your cloud rather than ours, and correlates signals automatically instead of leaving that to your engineers.

Can I try it alongside my current tools?

Yes. Start on the Free plan and run Modulis next to your existing stack while you evaluate. Your current alerts and dashboards keep working until you're ready to switch.

How much does Modulis cost?

Free forever to start. Starter is $199/month, Growth is $999/month, and Enterprise is custom. Every plan is a flat subscription with no ingestion-based billing. See the pricing page for details.

Is Modulis secure and compliant?

Modulis is VAPT certified. SOC 2 Type I and HIPAA compliance are in progress, expected December 2026. Because everything runs in your cloud, your data stays under your own security controls.
