Two-way sync
that can prove it.
Most tools claim two-way sync. We measured how they actually behave — phantom updates, silently vanishing edits, deletes that never propagate. SyncPair is a sync engine with a full audit trail: no edit is ever lost silently.
Your current sync is broken in ways it can't tell you about.
Before writing a line of product code, we instrumented the Airtable and Google Sheets APIs and ran naive two-way sync the way the popular automation tools do it. These aren't hypotheticals — every number below is a measured result.
Phantom updates
Insert a single row mid-sheet and position-based triggers report every shifted row as “edited.” Sorting flagged 5 of 6 untouched rows. With sync running, each phantom becomes a real write to the other side.
Conflicts decided by luck
Two people edit the same record within one poll cycle. The “winner” is whichever poll happens to fire first. The losing value appeared in no event, no log, no history — it simply ceased to exist.
Deletes are invisible — or worse
An Airtable delete produces zero events, ever. A Sheets delete fires a storm of fake “edits” to every row below it — and can silently hand the dead row's identity to its neighbor.
Stability by accident
When a naive sync loop “works,” it's because of an undocumented platform quirk — not design. One type coercion, one timestamp column, one trailing space, and it echoes forever: a write per minute, silently burning quota.

An engine that owns the truth — not glue that hopes.
The platforms give you snapshots, not events: no changed-field list, no old values, no writer identity. Reliable sync means the engine keeps its own state. Every component below exists because a measured failure demanded it.
Identity ledger
Every record mapped by durable ID — survives inserts, sorts, and renames without duplicates or orphans.
Echo suppression
Origin-tagged writes and content hashing. Our own writes can never boomerang back as “changes.” No loops, by design.
Conflict journal
Concurrent edits are detected, both values are kept, your policy picks the winner — and the loser is never silently discarded.
True delete handling
Deletes are detected by ledger sweep, propagated exactly once, and tombstoned so they can never resurrect from the other side.
Restart-safe
Downtime backlog replays through the same audited pipeline — no double-applies, no catch-up floods, no ghost records.
Audit feed
Every synced change, conflict, and delete in one reviewable trail. When someone asks “what touched this record?” — you have the answer.
