Event-driven workflow platform

Information should flow.
Not leak.

Every action in Flow3 becomes an event. Every event drives the next step. Reviews, approvals, markups — connected in one unbroken flow. Across teams. Across devices. With zero information loss.

One flow. Five stages. Zero gaps.

Every workflow item follows a clear, event-driven pipeline. Each transition is tracked, attributed, and reversible.

Event-Driven Transitions

Each stage change fires an event. Downstream stages react automatically. Reviewers are notified on submit. Submitters are notified on release. No manual follow-up needed.

Complete Audit Trail

Who submitted. Who reviewed. Who released. When, from which device, with what severity. Every action is permanently attributed and timestamped.

Stop sharing screens.
Start sharing context.

Coflow lets your entire team navigate the same item, the same review, the same page of the same PDF — simultaneously. One person drives. Everyone follows. In real time.

Session-Based

Create a session. Invite your team. Navigate together across flows, items, reviews, and files.

Full History

Every navigation event is logged. Replay any session for auditing or onboarding.

Graceful Offline

Lost connection? Switch to solo mode seamlessly. Rejoin when you're back.

DAR-2024 Item #1024 Review R3 drawing-v2.pdf p.4

No org chart required.
Just the right access.

Roles in Flow3 are per-member, per-flow. The same person can be a Reviewer in one flow and a Submitter in another. No rigid hierarchy. No global admin bottleneck.

Cross-Organization

Invite external stakeholders. Each sees only what their role permits.

Contextual Permissions

Access is scoped to each flow. No cross-flow data leakage.

Full Attribution

Every action stamped with who, when, and from which device.

Not responsive. Adaptive.

Flow3 doesn't just shrink to fit. It restructures itself — from single-pane mobile to three-column desktop — adapting the information architecture to your screen.

Built different. Not just marketed different.

Flow3 runs on a reactive, event-driven architecture that eliminates the state desync bugs plaguing traditional workflow tools.

Reactive Streams

Database changes emit to UI automatically via Drift watch streams. No manual refresh. No stale cache.

Hybrid Sync

Real-time WebSocket for instant updates. Polling fallback catches anything missed during connectivity gaps.

DB-Driven Navigation

Navigation state lives in the database. Switch devices — your exact position is preserved.

Action-DB-UI Pattern

One tap = one DB write = one stream event = one UI update. Zero side effects. Guaranteed consistency.

Local-First Storage

SQLite is the single source of truth. Work offline. Sync when connected. Data is always available.

Material Design 3

Dynamic theming with Google Sans Flex. Platform-native colors. Smooth dark/light transitions.

Your workflow deserves
to actually flow.

Join teams who've moved from scattered tools to one unified, event-driven platform. Free to start.
