Open TMS

Overview

Open TMS is an open-source platform for coordinating freight and warehouse operations from order intake to delivery. It suits shippers, 3PLs, carriers and warehouse teams that need those workflows together. Its breadth is compelling at no software charge, but deployment and setup call for technical ownership or consultancy support.

Key features

Transportation and carrier operations

Teams can bring orders in by CSV, EDI 850, REST API or manual entry, then manage tracking, lane matching and multi-stop routing. Broadcast and waterfall tenders, a carrier bidding portal and EDI tendering give operations options for sourcing capacity. This range fits businesses with varied carrier processes better than teams that only need a basic shipment-tracking view.

The EDI hub supports X12 850, 855, 856, 204, 990, 997, 214, 210, 810 and 820 transactions over SFTP or HTTP. FedEx, UPS and DHL tracking integrations use OAuth 2.0 or API keys. GPS and sensor data feed traffic-aware ETA monitoring through TomTom, HERE or self-hosted Valhalla routing. These connections make the system relevant to operations joining order, carrier and location workflows.

Warehouse, mobile and compliance

The warehouse module covers receiving, putaway, picking, packing, load planning, inventory and returns alongside orders and shipments. A scan-first progressive web app supports warehouse work and barcode scanning with Zebra and Honeywell RF guns through a barcode wedge hook. That shared operational scope can reduce the need to separate warehouse and freight processes, while the breadth may be unnecessary for a business focused solely on transportation.

For temperature-sensitive operations, the maker describes CFR 21 Part 11 compliant temperature logging with SHA-256 integrity hashes, excursion detection and automatic quarantine workflows. Developer webhooks use HMAC-SHA256 signatures, a five-minute tolerance window and exponential-backoff retries up to five attempts. These are targeted controls for regulated or integration-heavy workflows, rather than a substitute for evaluating an organization's full compliance requirements.

Deployment and support

Open TMS can be deployed with Docker Compose on AWS, GCP, Azure, DigitalOcean or self-hosted infrastructure. That flexibility is useful for organizations with infrastructure preferences, but it also means buyers should plan for deployment and configuration. Professional installation, setup and ongoing support are offered as consultancy services.

Pricing

The Open TMS plan costs nothing, billed Free forever. It is MIT licensed and has no per-user fees, transaction costs or feature gates. Inventory tracking, shipment tracking, order management and document management are included. This removes common usage-cost barriers as teams grow, but it does not remove the operational work of deploying and setting up the system. Consultancy services are available for organizations that want installation, setup or ongoing support.

Platforms

Open TMS supports API, self-hosted and web use. Its deployment options span Docker Compose, major cloud providers and self-hosted infrastructure; warehouse users also have a progressive web app for mobile scanning workflows.

Who it's for

Open TMS is aimed at shippers, 3PLs, carriers, warehouse teams, quality managers and compliance officers. It is strongest for organizations that want order, shipment, inventory and warehouse processes under one open-source system and can take responsibility for deployment. Teams without that technical capacity should weigh the available consultancy support or consider a paid service with a deployment model better suited to their needs.

Pros and cons

• Pros: A free-forever, MIT-licensed plan with no per-user fees, transaction charges or feature gates keeps software costs predictable.
• Pros: Order intake, carrier tendering, tracking, inventory and warehouse workflows coexist in one system.
• Pros: Multiple EDI transaction types, carrier API integrations and routing options support varied operational connections.
• Cons: Deployment and setup require planning; professional installation and ongoing help are consultancy services.
• Cons: Its broad transportation and warehouse scope may be more than teams needing only a narrow tracking tool require.

Alternatives

Logistics Management Software is a useful category to explore when comparing systems across the broader logistics field.

Choose Fleetbase instead if you want a freemium product with a free trial, Android and iOS apps, or a cloud plan at $29 a month billed monthly that includes unlimited orders and users.

Made4net WMS is a paid warehouse-focused alternative with custom pricing based on features, warehouse size and cloud or on-premise deployment.

Shipwell TMS is a paid alternative for teams considering a transportation management system with customized quote pricing through sales.

Manhattan Active Inventory Replenishment is a paid option for teams seeking an inventory replenishment product rather than Open TMS's combined freight and warehouse scope.

project44 Ocean Visibility may suit teams focused on ocean visibility, with a Movement UI or API and 150+ ocean carrier and forwarder connections.

e2open Transportation Management is another paid transportation management option for teams comparing API and web platforms.

Flexport Control Tower is a paid API and web alternative for teams evaluating a control-tower product.

Verdict

Choose Open TMS if your operation needs transportation and warehouse workflows together and can manage its own deployment. Its open-source, free-forever plan avoids per-user and transaction costs while covering a broad logistics lifecycle. Look elsewhere if you want a narrower tool or need an operating model that does not depend on your team handling setup.
