Mosaic alternatives are worth comparing when project organisations still need forward workload visibility but want a different balance of scheduling simplicity, skills, scenarios, integrations, or financial control.
What Mosaic still does well
Mosaic's current feature documentation separates member workload from project planning and supports capacity in hours or percentages, office and discipline groupings, unassigned role work, dependencies, time off, and budget-connected planning.
Keep Mosaic when moving between the project and person views matches how the organisation plans. Do not replace it until the next option proves generic-role demand, dependencies, history, and integration continuity.
Best Mosaic alternatives
| Alternative | Prefer it when | Main trade-off |
|---|---|---|
| Runn | Tentative work and what-if capacity scenarios are primary | Project-planning depth differs |
| Float | A simpler live visual people schedule is enough | Project dependencies and role planning may be lighter |
| Saviom | Enterprise pools, skills, financial modelling, and optimisation are required | Rollout and governance effort rise sharply |
| Hub Planner | Skills-based scheduling and project reporting fit better | Assess the current Milient Resource Flow boundary |
| Kantata | Staffing must connect to wider PSA delivery and economics | It is a broader transformation |
| A focused allocation operation | Mosaic can plan capacity but requests and commitments need controlled evidence | Integration and operations remain yours |
Apps like Mosaic: test both views
Create unnamed role demand, assign it, introduce leave and a dependency shift, then inspect the effect in project and workload views. Prove permissions, change history, stale-data handling, budgets, exports, and reconciliation.
Free or open-source Mosaic alternatives may cover schedules or Gantt charts but rarely remove the cost of a coherent capacity model, integrations, security, audit, backups, and support. Smaller firms should favour the lightest product that preserves their real planning decisions.
Switch, keep, or own the control plane
Switch when the project-and-capacity model itself is wrong. Keep Mosaic when source data or planning cadence is the actual problem. Own a focused operation when people, leave, projects, finance, and time can stay authoritative but demand versions, candidate evidence, approvals, commitments, exceptions, and reconciliation are missing.
Before replacing Mosaic
Inventory people, offices, disciplines, roles, skills, availability, projects, phases, dependencies, milestones, generic demand, work plans, budgets, time off, integrations, reports, permissions, and history. Require the target to reproduce both a project-centred and member-centred planning case. Parallel-run one live planning period, reconcile dates, workload, unassigned demand, capacity, and budget effects, and test correction and deletion behaviour. Preserve exports and a rollback path until downstream systems accept every committed change reliably.
The practical decision
Choose Runn or Float when you can simplify the planning model. Choose Saviom or Kantata only when enterprise optimisation or PSA economics are genuine requirements. Keep Mosaic when its project-and-person views match the operating cadence. If the pain sits between request and commitment, preserve the planner and own that smaller operation instead of forcing a platform migration.
Questions the shortlist must answer
Can a planner move between the project timeline and an individual's workload without reconciling two models? How are generic role demand, skills, dependencies, and time off represented before a person is named? Can project leaders propose changes without overwriting an approved staffing plan? Require the same answers for API data and exports as for the interface; otherwise the new view may conceal another manual planning layer.
