OpenProject vs Harvest: at a glance
What is OpenProject?
OpenProject grinds out steady releases while hardening against a bug-bounty backlog of CVEs.
OpenProject is in a maintenance-heavy stretch: a run of 17.x point releases mixes small features with a steady stream of security patches surfaced by its EU-sponsored bug bounty. Feature work is incremental but pointed — project-based work package identifiers ease Jira migrations, and 17.6 adds an XWiki integration linking project management to enterprise knowledge. The cadence is high but a large share of releases are corrective.
What is Harvest?
Harvest rebuilt its interface and split off a Premium tier for profitability
Harvest is mid-rollout of 'the new Harvest,' a full interface redesign paired with a paid Premium plan (profitability reporting, activity log, SAML SSO), task-level scheduling in Forecast, and reworked invoice sending. Its changelog reads as marketing-heavy blog posts and SEO articles rather than granular release notes, with several near-duplicate posts per release.
OpenProject vs Harvest: editorial side-by-side
OpenProject grinds out steady releases while hardening against a bug-bounty backlog of CVEs.
◆ Current state
OpenProject is in a maintenance-heavy stretch: a run of 17.x point releases mixes small features with a steady stream of security patches surfaced by its EU-sponsored bug bounty. Feature work is incremental but pointed — project-based work package identifiers ease Jira migrations, and 17.6 adds an XWiki integration linking project management to enterprise knowledge. The cadence is high but a large share of releases are corrective.
◆ Where it's heading
The product is consolidating as a credible open-source Jira alternative rather than chasing new categories. Recent features — Jira-friendly identifiers, XWiki knowledge links, Baselines refinements — target enterprise buyers weighing a migration. Security discipline, with multiple CVEs patched across back-ported 17.2 through 17.4 lines, signals a push for enterprise trust.
◆ Prediction
Expect continued 17.x point releases pairing migration-friendly features with back-ported security fixes; the Jira-migration and enterprise-knowledge threads are the ones to watch build out.

Harvest rebuilt its interface and split off a Premium tier for profitability
◆ Current state
Harvest is mid-rollout of 'the new Harvest,' a full interface redesign paired with a paid Premium plan (profitability reporting, activity log, SAML SSO), task-level scheduling in Forecast, and reworked invoice sending. Its changelog reads as marketing-heavy blog posts and SEO articles rather than granular release notes, with several near-duplicate posts per release.
◆ Where it's heading
The redesign is the surface; the deeper move is upmarket. Profitability insights, SSO, and a Premium tier target agencies and larger teams that need margin visibility, not just time entry. Harvest is repositioning from a timesheet tool toward a project-profitability system, with invoicing and Forecast scheduling as supporting pieces.
◆ Prediction
Expect the new interface to finish rolling out to all accounts and more Premium-only reporting to follow the Profitability tier.
