ISO8583Studio Pro

Early access

The studio stays free. Pro raises the ceiling: higher cryptographic throughput, the full algorithm set, deeper tuning of every simulator — plus hosted endpoints, certification-grade test packs and an engineer to call when a cryptogram won't verify.

What Pro adds

Higher cryptographic throughput

Raised CPS ceiling — the free build throttles cryptographic operations per second; Pro runs multi-threaded across cores for load and soak testing at production-like rates.

Full algorithm set

Beyond the free 3DES/AES basics: RSA and ECC key operations, SHA-3, FPE (FF1/FF3-1), Poly1305, ChaCha20, DUKPT AES, and vendor-specific key derivations.

Deep simulator tweaks

Per-field ISO 8583 overrides, custom bitmap and header handling, latency and error injection, partial-response and timeout scenarios, and editable payShield command behaviour.

Hosted simulator endpoints

Host, HSM and switch simulators running as always-on endpoints with static addresses, so pipelines and remote teammates hit the same test bed instead of someone's desktop.

Scheme certification packs

Curated Visa, Mastercard, RuPay and NPCI message sets with expected responses, run as a suite with a pass/fail report you can attach to a certification submission.

Unlimited scripted suites

Chain transactions, assert on any field or TLV tag, parameterise with data files, and run the whole thing headless from the CLI in CI.

Team configuration sync

Share gateway, HSM and terminal configurations across a team with versioning and rollback, instead of passing YAML files around.

Full HSM key ceremony

Extended payShield command coverage, LMK sets per environment, TR-31 key blocks, component printing and audited key ceremonies.

Priority engineering support

Direct channel to the engineers who wrote the simulators, with same-business-day response and help reading real traces.

Free
All 9 simulators, all 64 tools, standard algorithms, throttled cryptographic throughput, local configs, manual test runs, community support on GitHub.
Pro
Everything in Free, plus a raised CPS ceiling, the full algorithm set, deep per-simulator tweaks, hosted endpoints, certification packs, scripted suites in CI, config sync, extended HSM coverage and priority support.

Tell us who you are and what you're certifying. We provision your workspace and send credentials by email.

Pay what Pro is worth to you. Early access is provisioned from a queue — the higher the amount, the higher your priority in it, so a larger contribution gets your workspace, certification packs and support channel opened sooner.

Higher amount → higher priority in the early-access queue. GST is added at checkout.

Questions

Does the free studio change?

No. Every simulator and tool that is free today stays free, offline and unrestricted. Pro is additive.
