octoplant vs Copia: Approved Versions or Git-Native PLC Source Control

octoplant vs Copia is the comparison most buyers in North America now ask about. Both tools back up PLC programs, keep versions, detect changes and restore. They differ in the model underneath. octoplant, from AMDT, is built around an approved version of each device, with check-out and check-in around edits. Copia Automation is built on Git, the version control system software teams use, with a device agent called DeviceLink that pulls running code into the same store. This page compares them on public facts as of October 2026 and says where each fits. It does not name a winner. The right answer depends on the plant’s vendors, its people and where its data may live.

octoplant vs Copia: two models of change

octoplant’s approved-version model. An engineer checks out the approved version, edits it in the native engineering tool, and checks it back in. Scheduled jobs upload from the device and compare against the approved version, flagging planned, accidental or unauthorized changes (amdt.com). Roles and approval workflows sit on top. The question the model answers is: does the device still match what we approved?

Copia’s Git-native model. Copia describes “Git-based versioning for industrial code” and a platform to “monitor, approve, backup, and recover your industrial code” (copia.io). Engineers commit changes, keep history and compare versions in the way a software team would. DeviceLink adds the device side: it “automatically backs up PLC control programs on a schedule or on demand” and “continuously monitors code at the machine level, detecting modifications as they happen” (DeviceLink). The question the model answers is: what is the full history of this code, and how did it get here?

The models are closer in practice than in principle. Copia’s source control includes in-line comments and approval workflows before a change is merged (Copia), and octoplant keeps a full version history behind each approved version. The real difference is what each treats as the reference: octoplant an approved state per device, Copia a branch of the code’s history.

Deployment, and what DeviceLink means for the network

DeviceLink is an agent with an outbound connection. Copia states that the agent “installs on your manufacturing network” and “communicates with the Copia servers via outbound HTTPS” (DeviceLink). For many plants that is acceptable and simpler than running a server. For others it is a network design question: which zone the agent sits in, what it can reach, and what crosses the boundary. Our guide to OT network segmentation in a brownfield plant covers the zones involved.

Copia is widening its deployment options. Its June 2026 funding announcement said it would support “cloud, customer-managed data centers, and air-gapped environments” (Pulse2). Ask which of these is generally available for your site today.

octoplant runs where the plant puts it. It is mainly an on-premises product, with server, clients and agents that bridge separated subnets, and a first browser interface in release 105. The detail is on octoplant Architecture.

AI, funding and scale

AI. Copia lists Copia AI (documented as Copilot) for code analysis and Copia Actions for automation workflows. TNW described part of the platform as “a continuous-delivery system, essentially GitHub Actions for industrial code” (TNW). AMDT’s line is “AI is optional. Control is not.” (amdt.com), with an on-premises Companion chat and AI vulnerability guidance; see AI Companion.

Funding and scale. Copia raised $26,000,000 in June 2026, led by AE Ventures and Squadra Ventures, bringing its total to $55,000,000 (Pulse2). AMDT states more than 3,200 customers (amdt.com) and traces its roots to 1987. One is a fast-growing, well-funded challenger; the other an established installed base. Both facts matter to a buyer planning a ten-year tool.

Where each fits

Copia tends to fit when:

• Engineering teams already use Git, branches and reviews, or want to
• Cloud hosting with an on-site agent is acceptable to IT and OT security
• The estate is mostly the PLCs, PanelView HMIs and FANUC robots on Copia’s published matrix
• The team wants to check coverage in public documentation before talking to sales

octoplant tends to fit when:

• Robot brands beyond FANUC, CNC, drives and network devices need native protection alongside PLCs
• The data must stay on-premises today
• Technicians and contractors edit on shift, and a check-out and approval model suits them
• The plant runs versiondog or AutoSave, where octoplant is the successor

A plant scenario (illustrative). A food plant runs twenty Rockwell and Siemens PLCs, eight robots and a packaging line from an OEM whose integrator still holds the latest code. Its controls team of four already keeps HMI scripts in Git. Copia would suit how that team works on the PLCs, and covers the robots if they are FANUC. If they are another brand, octoplant’s stated coverage is wider. Either way the decision turns on whether those eight robots and their drives are covered adequately, and that is a proof-of-concept question, not a brochure question.

Questions to ask both vendors

1. Which of our device models and firmware versions do you support today, in writing?
2. Where are backups, credentials and audit logs stored, and who can reach them?
3. How long does a full restore of one controller take, end to end, without the engineering laptop that last touched it?
4. What happens when the engineering software version on the device is one we no longer have installed?
5. What does migration from versiondog, AutoSave or the other vendor’s tool bring across, history included?
6. What does the AI feature send outside the site, if anything?

Where it gets hard

Git is a skill, not a feature. Branches and merges help teams that understand them and confuse teams that do not. Ask who on site will resolve a conflict between two edits at three in the morning.

An approved version needs an approver. octoplant’s model works only if someone owns approvals. Without that, the approved version drifts as surely as an unmanaged server copy.

Restore is the test. Both vendors make recovery claims. Time a restore of one controller from each tool alone during the proof of concept; see Disaster Recovery.

Coverage lists move. Copia added Omron Sysmac Studio in 2026 and publishes its matrix; AMDT’s is gated behind a login. Note too that a product can version a vendor’s files without backing up the device: Copia’s matrix separates Git support from DeviceLink backup, and some vendors have only the first. Test your hardest devices, not the logo list.
