How TruePPM Compares

This page names competitors and cites sources. It also names the comparisons TruePPM loses, because a comparison page that only lists wins is an advertisement, and you should not make a tooling decision on an advertisement.

How to read the claims here

Claims about other tools are dated and linked. Vendor packaging changes — re-verify against the linked source before quoting any of this. Claims about TruePPM’s own capabilities are checkable against the engine package and the tested scale envelope. If a row here is wrong, open an issue and we will correct it.

The one-sentence version

TruePPM is the only open-source PPM platform we are aware of that ships Monte Carlo schedule risk analysis, and the only PPM tool of any kind — open or commercial — whose scheduling engine you can install and audit by itself. It is not a Primavera P6 or MS Project replacement, because it has no resource leveling and one constraint type.

Against the open-source field

	CPM with float	Monte Carlo	Agile board coupled to the schedule	Engine installable standalone	OIDC/OAuth login in the free core
TruePPM	Yes	Yes	Yes — same object	Yes (pip install trueppm-scheduler)	Yes (ships in 0.4) 1
OpenProject	Gantt with dependencies and automatic scheduling	No	Board and Gantt as adjacent views	No	Enterprise add-on 2
Redmine	Via third-party plugins	No	No	No	Third-party plugin 3
Plane	No	No	Agile-only	No	Paid / Commercial editions 4
Taiga	No	No	Agile-only	No	Third-party plugin 5
Leantime	No	No	No	No	Yes — free in the core 6
ProjectLibre / GanttProject	Yes (desktop)	No	No	No	n/a — desktop, no server auth

Three things this table is really saying:

Monte Carlo is the empty column. Probabilistic schedule risk is absent from the entire open-source PPM field. That is TruePPM’s sharpest single differentiator and the easiest one to verify — install the engine and run it.

The agile/waterfall split is a real fork, and most tools pick a side. Plane and Taiga are agile-only; ProjectLibre and GanttProject are schedule-only. OpenProject carries both, but as adjacent views over related records rather than one coupled model. In TruePPM the board card and the Gantt bar are the same row — close a sprint and measured velocity reforecasts the CPM finish.

Leantime deserves credit on SSO. It is the one open-core tool in this field that does not charge for OIDC login. Only SAML is a paid add-on. ⁶ The SSO tax page covers the full picture.

Against the commercial scheduling tools

This is where the honest losses are.

	TruePPM	Primavera P6	MS Project
CPM, 4 dependency types, calendar-aware lag	Yes	Yes	Yes
Monte Carlo risk	In the core	Separate product (Primavera Risk Analysis)	Separate product (third-party)
Resource leveling	No	Yes	Yes
Constraint types	1 (start-no-earlier-than)	Full set	8 + deadlines
Cost / earned value	No (EV-lite planned 0.8)	Yes	Yes
Tested task ceiling	~1,000 in the Schedule view	Very large (100k+ activities in practice)	Large
Sub-day scheduling	No (planned 0.6)	Yes	Yes
Agile board / sprints	Yes, on the same objects	No	No
Real-time multi-user web	Yes	Limited	Limited
REST API + WebSocket, API-first	Yes	Partial	Limited
Self-hosted, no per-seat license	Yes, Apache 2.0	No	No
Engine auditable standalone	Yes	No	No

Do not choose TruePPM over P6 or MS Project if you need resource leveling, must-finish-on constraints, earned value, sub-day durations, or schedules beyond a few thousand tasks. Those are real capabilities that real schedulers depend on, and TruePPM does not have them. See What TruePPM doesn’t do yet.

Do choose TruePPM over them if you want a schedule that lives on your own infrastructure with a real API, a team that works in sprints without the PM maintaining a parallel plan, probabilistic forecasts without buying a second product, and an engine you can verify rather than trust.

On Monte Carlo pricing

Across the commercial field, probabilistic schedule risk is a separately licensed product that operates on a schedule exported from your scheduling tool: Deltek Acumen Risk, Barbecana Full Monte, Safran Risk, and Oracle Primavera Risk Analysis are the common ones. We do not publish price comparisons because these vendors mostly do not publish list prices — but “separately licensed product” is the structural point, and it is checkable from each vendor’s own product pages.

TruePPM computes P50/P80/P95 and per-task sensitivity in the same engine that computes the deterministic dates, in the free core, with no export step. You can confirm that in sixty seconds:

pip install trueppm-scheduler

Against Jira

Jira is not a scheduling tool and does not claim to be, so the comparison is narrow but it is the one most teams actually face.

Jira + Advanced Roadmaps does capacity-based planning across teams. It does not compute a critical path, float, or a probabilistic finish date. TruePPM does all three, on the same task objects your team moves across a board.

TruePPM’s answer to Jira is deliberately not “switch.” A personal, read-only, one-way Jira sync into My Work ships in 0.4 so contributors never double-enter, and a one-time migration import follows in 0.5 for teams that decide to move. Run both and get the CPM forecast without asking anyone to change tools first.

Where Jira wins and will keep winning: ecosystem, marketplace, integration breadth, and developer familiarity. TruePPM’s plugin architecture is planned for 0.7 and a public Extension SDK for 0.9.
