Onplana vs Microsoft Project Online (2026): Feature-by-Feature Comparison
Direct comparison of Onplana and Microsoft Project Online across scheduling, governance, AI, integrations, and pricing. Built for PMOs migrating ahead of the September 30, 2026 retirement.
Onplana vs Microsoft Project Online: Feature-by-Feature Comparison for 2026
Microsoft Project Online retires on September 30, 2026. If you're running PWA today, you have around five months to land on a replacement that covers everything your PMO actually uses, the Gantt schedules with FS/SS/FF/SF dependencies, the enterprise custom fields, the resource pool with cost rate tables, the governance gates, the CCB workflow, the audit trail, the SSO. Pick wrong and migration day finds the gap.
This post is the direct head-to-head: Onplana vs Project Online, feature by feature, with the parity status, the gaps that matter, and the gaps that don't. If you're earlier in the decision process, the Microsoft Project Online End-of-Life timeline frames the urgency, and Best Microsoft Project Alternatives in 2026 is the wider market scan.
📌 TL;DR: At a glance
- Schedule fidelity: parity. Same dependencies, same baselines, same critical path, with a faster Gantt.
- Resource pool + governance: parity. ECFs, lookup tables, cost rate cards, multi-reviewer gates, CCB.
- AI: Onplana has it. Project Online does not.
- Modern UX: real-time collaboration, mobile, dark mode, unified workspace. Project Online is 2014-era SharePoint UX.
- Microsoft 365 integration: Onplana imports OData, Planner, Project for the Web; bi-directionally syncs with To Do per project list. Project Online itself is being retired, so its integrations are sunsetting too.
- Pricing: ~80% cheaper at the BUSINESS tier vs Plan 3. Free tier exists.
- Migration: native .mpp + OData wizard. Most PMOs land in 8-12 weeks.
Schedule planning + Gantt: feature parity, modern execution
For most PMOs evaluating a Project Online replacement, this is the make-or-break category. If schedules don't move 1:1, the migration is dead in the water.
| Capability | Project Online | Onplana |
|---|---|---|
| Gantt chart with hierarchical tasks | Yes | Yes (PRO+) |
| All 4 dependency types (FS / SS / FF / SF) | Yes | Yes |
| Dependency lag values | Yes | Yes |
| Critical path calculation | Yes | Yes |
| Multiple baselines per project | Yes (up to 11) | Yes (unlimited; named snapshots) |
| Baseline overlay on Gantt | Yes | Yes |
| Milestone markers | Yes (diamonds) | Yes (diamonds) |
| Auto-schedule from constraints | Yes | Yes |
| Resource leveling | Yes | Yes (with preview before apply) |
| Calendar exceptions per resource | Yes | Yes |
| Date-only fields (no TZ shifts) | Yes | Yes (UTC-pinned per CLAUDE.md note 71) |
| Working calendars with templates | Yes | Yes (Mon-Fri / Mon-Sat / 7-day + custom) |
Where Onplana edges ahead: drag-to-reorder Kanban, Calendar, and Burndown views all share the same task model, so a task moved on Kanban updates the Gantt instantly. Project Online's view-switching requires save-publish round-trips. Onplana's Gantt also renders the baseline as a phantom row INSIDE the Gantt (not as a separate "compare" mode), so drift is visible without a mode switch.
Where Project Online edges ahead: the Project Desktop client has decades of muscle memory for power users doing complex schedule edits. Onplana's web-only Gantt is faster but unfamiliar to Desktop diehards for the first week.
Custom fields + lookup tables: full parity, no silent loss
The single most common gap in Project Online replacements is custom-field fidelity. Onplana matches the three-axis attachment model (Project / Task / Resource) and supports hierarchical lookup tables natively.
| Capability | Project Online | Onplana |
|---|---|---|
| Project-level enterprise custom fields | Yes | Yes (CustomFieldDefinition entityType=PROJECT) |
| Task-level enterprise custom fields | Yes | Yes (entityType=TASK) |
| Resource-level enterprise custom fields | Yes | Mapped to user profile fields |
| Field types (text, number, cost, date, flag, lookup) | 6 types | 6 types (TEXT, NUMBER, COST, DATE, CHECKBOX, DROPDOWN, MULTI_SELECT) |
| Multi-line text fields | Yes | Yes (TEXT_LONG) |
| Required-field enforcement | Yes | Yes |
| Lookup tables (flat) | Yes | Yes (DROPDOWN / MULTI_SELECT) |
| Lookup tables (hierarchical, parent-child) | Yes | Yes (Tag tree with parent/child) |
| Calculated fields | Yes (Project formula language) | Snapshot value migrates; formula recreates in destination expression engine if needed |
| Multi-value lookup auto-split (";#" delimiter) | N/A | Yes (importer handles natively) |
| Currency-typed cost fields | Yes (org-default currency) | Yes (per-field currency lock; survives multi-currency rollups) |
The full migration path is in Project Online Custom Fields Migration, including the audit-on-the-source-side pass that typically retires 40-60% of dead-weight fields before migration even starts.
Resource pool + capacity: full parity with cleaner UX
Project Online's Enterprise Resource Pool, cost-rate tables, and per-resource availability all have direct equivalents in Onplana.
| Capability | Project Online | Onplana |
|---|---|---|
| Tenant-wide resource pool (one resource, many projects) | Yes | Yes (organisation members) |
| Generic resources (role placeholders) | Yes | Yes (project roles + role-keyed rate cards) |
| Material + cost resources | Yes (Material, Cost types) | Modeled separately as expense categories / budget lines |
| Cost rate tables A through E | Yes | Table A maps directly; B-E supported via labeled rate cards |
| Date-tiered rates (effective from / to) | Yes | Yes (RateCard with effectiveFrom + effectiveTo) |
| Per-resource availability calendars | Yes | Yes (WorkingCalendar with per-user assignment) |
| Per-resource calendar exceptions (vacation, sick) | Yes | Yes (CalendarException model) |
| Capacity planning (weekly hours per resource) | Yes | Yes (ResourceCapacity model + Capacity Planner UI) |
| Cross-project workload visibility | Yes | Yes (Resources page + over-allocation detection) |
| Timesheets with approval workflow | Yes | Yes (per-week submit, manager or designated-approver mode) |
| Historical timesheet retention | Yes | Yes (with FX-snapshot per-entry for stable historical reports) |
The detailed migration path for the Enterprise Resource Pool, including the 5-step inventory-deduplicate-export-import-validate flow, is in Project Online Resource Pool Migration.
Governance + CCB: first-class on both, modern execution on Onplana
| Capability | Project Online | Onplana |
|---|---|---|
| Multi-stage proposal workflow | Yes (custom EPT) | Yes (12 stages, ENTERPRISE+) |
| Multi-reviewer gate approvals | Yes (workflow approval) | Yes (designated reviewers per gate, quorum logic) |
| Gate reviewer panels (per gate type) | Yes | Yes (PROPOSAL_REVIEW / BUSINESS_CASE_REVIEW / PLAN_REVIEW) |
| Project auto-creation from approved proposal | Yes | Yes (configurable: at approval, at business case, at plan) |
| Change Control Board (CCB) | Custom build via SharePoint | First-class feature (ENTERPRISE+) |
| Formal change request workflow | Custom build | Yes (DRAFT → SUBMITTED → REVIEWED → APPROVED / REJECTED → IMPLEMENTED) |
| Designated CR reviewers | Custom build | Yes (ChangeRequestReviewer + threshold) |
| Audit trail per gate decision | Yes | Yes (ProposalReview + AuditLog) |
| Sponsor notifications | Custom build | Yes (built-in on every stage transition) |
| Project↔Proposal lifecycle bridge | Manual | Auto-sync (status changes propagate both ways) |
Verdict: where Project Online required custom SharePoint workflow + Power Automate to build CCB, Onplana ships it as a first-class feature with the audit trail and notifications already wired.
AI: Onplana has it; Project Online does not
This is the single largest gap.
| Capability | Project Online | Onplana |
|---|---|---|
| AI plan generation (idea → tasks/subtasks/risks) | None | Yes (PRO+) |
| AI risk detection (analyses tasks, timeline, team) | None | Yes (BUSINESS+) |
| Natural-language task parsing ("schedule design review next Tuesday") | None | Yes |
| AI status report generation | None | Yes |
| AI Project Kickstart (first-run onboarding) | None | Yes |
| Per-org AI cost ledger + admin caps | N/A | Yes |
| Dual-provider (Anthropic + Azure OpenAI) admin choice | N/A | Yes |
| Per-endpoint model overrides | N/A | Yes |
Project Online predates Microsoft Copilot, and Microsoft has explicitly not added Copilot to Project Online (the investment has gone to Project for the Web). For PMOs evaluating tools by AI capability, this is a one-sided comparison.
Modern Microsoft 365 integration: Onplana imports from all three
Project Online itself is being retired. The integration story for organisations staying on Microsoft 365 is now Project for the Web (Premium), Microsoft Planner (consolidated app inside Teams), and Microsoft To Do. Onplana imports from all three.
| Integration | Project Online | Onplana |
|---|---|---|
| Microsoft Planner import | N/A (different product) | Yes (Microsoft Graph, basic-tier with optional live sync) |
| Project for the Web (Premium) import | N/A (different product) | Yes (Dataverse path; brings dependencies + effort) |
| Microsoft To Do bi-directional sync | N/A (different product) | Yes (per-project lists + subtasks as checklist items) |
| Microsoft Teams notification cards | Limited | Yes (project.* and task.* events) |
| Microsoft Outlook calendar push | Limited (Project Server-side) | Yes (event sync per task with due date) |
| Microsoft Graph token refresh + revocation | N/A | Yes (built-in via OAuthConnection model) |
The Microsoft 365 imports are documented in:

Migration path: how it actually works
Onplana imports from Project Online via two paths, picked at the wizard step.
| Source | Method | What gets imported |
|---|---|---|
.mpp files (one per project) |
Drag-and-drop, in-process MPXJ parser for binaries, native parser for .xml (MSPDI) |
Tasks + dependencies (FS/SS/FF/SF + lag) + baselines + custom fields + resources |
| Project Online OData (whole tenant) | Connect via PWA URL + Microsoft 365 auth | Projects + tasks + assignments + resources + custom fields + lookup tables + calendars |
The full step-by-step is in How to Migrate from Microsoft Project Online. For the two technical sub-systems that drive most migration labor, see Project Online Custom Fields Migration and Project Online Resource Pool Migration.
Two free no-signup tools to derisk the migration before committing:
- Migration Preview — upload any .mpp and get a feature-by-feature compatibility report so the labor estimate stops being a guess.
- Migration Cost Calculator — 3-year TCO with low / mid / high scenarios, downloadable PDF for the CFO.
When NOT to pick Onplana
Honesty matters. Three cases where Project Online (or its successors) might fit better than Onplana:
You're already deep into Microsoft Power Platform for everything: Power BI dashboards driving executive meetings, Power Apps front-ends on top of Dataverse, Power Automate flows orchestrating everything. Project for the Web (Premium) inside the same Dataverse instance keeps the data model unified. Onplana imports from P4W if you decide to consolidate later, but if Power Platform IS your platform, Microsoft's stack is the natural choice.
You're a SharePoint-heavy organisation that uses PWA Project Sites as the primary collaboration surface for non-PMs (engineers reading specs, finance pulling cost reports). Onplana brings documents and wikis in-product, but if your wider company-wide knowledge base lives on SharePoint, the integration cost may not justify the move for that audience.
You're running scheduling at a scale Microsoft Project Desktop is uniquely built for: 5,000+ task schedules with complex resource leveling, manual constraint management by trained schedulers. Onplana handles this scale and the scheduling math is identical, but the muscle memory difference matters. For these orgs, the right migration is to Onplana for the cloud surface (PWA replacement) plus Project Desktop for the heavy-lifting schedulers (which Microsoft is keeping alive).

| AI assistance (plan-gen, risks, NL parsing) | Onplana |
| Free tier to derisk evaluation | Onplana |
| Lowest 3-year license cost | Onplana |
| Already deep in Power Platform | Project for the Web Premium |
| Lightweight task lists for non-PM teams | Microsoft Planner |
| Heavy SharePoint dependency for wider org | Project for the Web + SharePoint |
| Migration off Project Online before September 30, 2026 | Onplana (only tool with native .mpp + OData wizard) |
