① Comparison · mainframe developer tooling
This is not a choice between rivals. BMC acquired Compuware (BMC) in 2020 and rebranded the Topaz developer and test tooling as BMC AMI DevX. The products are one lineage under one owner. What differs is the contract era your entitlements sit in, and what BMC does with them at renewal.
Treat this as a reconciliation, not a product decision. BMC AMI DevX is the current branding of the Compuware Topaz stack, so there is no feature contest to settle and no real migration to fund. The exposure is contractual: as legacy Compuware schedules expire, BMC commonly repackages the entitlement onto current BMC AMI DevX terms, often subscription, often inside a wider BMC AMI relationship. The buyer side work is to map what you already hold under the old Compuware paper against what the new AMI DevX quote actually grants, component for component and seat for seat, before agreeing to anything. The naming change is the vendor's leverage. The contract reconciliation is yours.
The two columns are the same tools at two points in their naming history. The differences that matter sit in branding, packaging, and the contract model, not in function:
| Dimension | Compuware Topaz (heritage) | BMC AMI DevX (current) |
|---|---|---|
| Owner | Compuware, independent until 2020 | BMC, since the 2020 acquisition |
| Workbench | Topaz Workbench | BMC AMI DevX Workbench for Eclipse |
| Debug | Xpediter | BMC AMI DevX Code Debug |
| Source and release | ISPW | BMC AMI DevX Code Pipeline |
| Test and data | Topaz for Total Test, File-AID | BMC AMI DevX Total Test, File-AID |
| Fault analysis | Abend-AID | BMC AMI DevX Abend-AID |
| Common model | Perpetual plus maintenance on legacy paper | Increasingly subscription, often bundled in BMC AMI |
Directional and pattern level. Product names and packaging continue to evolve under BMC; confirm the current name, component list, and contract model against your own schedules before modeling a renewal.
Because there is no rival to pick, the decision is about how you handle the contract transition. Use it this way:
Hold the line on legacy Compuware terms if
Move to current BMC AMI DevX terms if
Either way, the foundational lever is the same: reconcile the old entitlement against the new quote line by line, confine the license to the developers who actually use the tools, and refuse any repackaging that quietly drops components you already paid for or extends term length in exchange for a headline discount.
No product contest here. The deal is won in the reconciliation.
