This is a repackaged open source software product wherein additional charges apply for hardening, security configuration, and setup support.
Appsmith is a self-hosted low-code platform for building internal tools, admin panels, dashboards and CRUD apps - a drag-and-drop UI builder backed by a Java server with embedded MongoDB, PostgreSQL and Redis, connecting to 25+ databases and REST/GraphQL APIs. This Lynxroute build is hardened and ready out of the box: per-instance secrets generated at first boot, the first signup becomes the administrator and further signups auto-close, HTTPS enabled by default, anonymous telemetry disabled, UFW firewall pre-configured, and a CIS Level 1 hardened Ubuntu 24.04 LTS base.
Apache-2.0 license - fully auditable, no vendor lock-in.
Overview
This is a repackaged open source software product wherein additional charges apply for hardening, security configuration, and setup support.
WHAT IS APPSMITH
Appsmith is an open-source low-code platform for building internal tools - admin panels, dashboards, CRUD apps, support consoles and approval workflows - without writing front-end code. You drag and drop from 45+ pre-built UI widgets (tables, forms, charts, lists, modals), bind them to data with a visual query editor, and add logic in plain JavaScript anywhere a value is accepted. It ships as a single all-in-one stack: a Java application server with an embedded MongoDB metadata store, PostgreSQL, and Redis, fronted by a Caddy reverse proxy. Appsmith connects to 25+ data sources, including PostgreSQL, MySQL, Microsoft SQL Server, MongoDB, Snowflake, Redis, Amazon S3, Google Sheets, REST APIs and GraphQL. Self-hosted means your apps, queries and data stay inside your own AWS account. Apache-2.0 license, no vendor lock-in.
WHAT THIS AMI ADDS
Security hardening:
- Per-instance secrets - the encryption keys and the embedded MongoDB, PostgreSQL and Redis passwords are generated at first boot, never baked into the image
- No administrator account baked in - the first user to sign up becomes the Instance Administrator, and a background service disables further signups automatically once the first admin is registered
- HTTPS enabled by default with a self-signed certificate (in-container Caddy reverse proxy); set a custom domain to switch to a built-in Let's Encrypt certificate
- Embedded MongoDB, PostgreSQL and Redis bound to localhost inside the container - never exposed on the network
- Anonymous usage telemetry disabled
- UFW firewall pre-configured - only TCP 22, 80, 443 are exposed
- fail2ban, AppArmor
- CVE scan - every image is scanned for vulnerabilities before release
OS hardening (CIS Level 1):
- CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
- auditd, SSH hardening, kernel hardening, IMDSv2 enforced
Compliance artifacts:
- SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
- CIS Conformance Report at /etc/lynxroute/cis-report.html
- CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md
NOTES
The full Appsmith stack (application metadata, your apps, and uploads) persists on a dedicated data volume across container restarts and instance reboots. On first launch the platform initializes its embedded databases, which takes a few minutes; a loading page is shown until it is ready. To move off the self-signed certificate, set APPSMITH_CUSTOM_DOMAIN to your domain in /etc/appsmith/appsmith.env to enable the built-in Let's Encrypt integration, then restart the service.
Highlights
- Appsmith security baked in: per-instance encryption keys and database passwords generated at first boot, no admin account baked into the image (the first signup becomes the Instance Administrator and further signups auto-close), HTTPS on by default, anonymous telemetry disabled, and the embedded MongoDB, PostgreSQL and Redis bound to localhost only.

Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Cost/hour |
|---|---|
t3.large Recommended | $0.05 |
m6i.large | $0.05 |
m6i.xlarge | $0.05 |
t3.medium | $0.05 |
Dimensions summary
You pay by the hour for the compute instance you run this hardened image on. The four options map to different AWS EC2 instance sizes, so pricing scales with the compute power you choose. The m6i.large and m6i.xlarge options use general-purpose instances, with the xlarge providing more capacity per hour. The t3.medium and t3.large options use burstable instances suited to variable workloads. All four deliver the same self-hosted low-code platform on a CIS Level 1 hardened Ubuntu base. You select the instance size that fits your workload and pay only for hours used.
Top-of-mind questions for buyers
The m6i.large and m6i.xlarge run general-purpose instances that hold steady compute. The t3.medium and t3.large are burstable, so they build credits when idle and spend them during spikes. Burstable suits variable usage; general-purpose suits steady, continuous workloads. You pick the type matching your usage pattern.
The hourly software charge meters running time only. A fully stopped instance does not accrue the software fee. You may still pay underlying AWS storage costs for the attached volume while the instance is stopped. Billing resumes when you start the instance again.
No. You pay only the hourly rate for the chosen instance size. The image runs entirely in your own cloud account with no telemetry or call-home. The vendor does not meter users, applications, or data. All billing is handled by the marketplace.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Appsmith v2.3
- Appsmith Community Edition updated to v2.3 (from v2.2) - low-code platform for internal tools and admin panels. Apache-2.0 unchanged
- Ask AI is now available in the Community Edition, and Custom Widgets gain a native AI Copilot; a new Card widget displays entities with a composable body canvas
- Appsmith AI data sources are deprecated: new ones can no longer be created after this upgrade, and existing ones stop working on 30 September 2026
- Security: fixes a datasource authorization bypass on application import and fork, symlink path traversal during Git import, permission groups crossing workspace boundaries, an open redirect on login, and an overly permissive frame-ancestors default
- FIXED: self-registration now really closes once the first account is created. Appsmith's own signup-disabled setting does not take effect on v2.3, so new accounts could still be created on an instance whose setup notes said registration was closed. Registration is now refused at the web server in front of the application, which does not depend on that setting. Inviting teammates is unaffected
- Registering the first account no longer restarts the application, removing a roughly five-minute outage that used to happen immediately after setup
- Rebuilt on the current CIS Level 1 hardened Ubuntu 24.04 LTS base to pick up the latest Ubuntu security updates
Additional details
Usage instructions
- Launch instance (t3.medium minimum, t3.large recommended for production)
- Open Security Group - allow TCP 443 from your IP (keep it restricted to your own IP until you have registered)
- SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
- Read the instance notes: sudo cat /root/appsmith-credentials.txt
- Open https://<PUBLIC_IP>/ in your browser - accept the self-signed certificate warning (allow a few minutes on first launch while the platform initializes; a loading page is shown until it is ready)
- Sign up - the FIRST account you create becomes the Instance Administrator
- Build your first app: add a datasource (PostgreSQL, MySQL, MongoDB, REST, GraphQL, and more), write a query, and bind it to drag-and-drop UI widgets
No administrator account is baked into the AMI - the first user to sign up becomes the administrator, and further signups are disabled automatically once the first admin is registered. Restrict Security Group port 443 to your own IP until you have registered, so nobody can claim the admin account before you. The platform serves HTTPS with a self-signed certificate by default. For a CA-signed certificate, set APPSMITH_CUSTOM_DOMAIN to your domain in /etc/appsmith/appsmith.env to enable the built-in Let's Encrypt integration, then restart the service with: sudo systemctl restart appsmith Per-instance encryption keys and the embedded database passwords are generated at first boot. Instance notes are saved to /root/appsmith-credentials.txt.
