吾年十三,建一免费离线优先之活动操作平台。此架构为何异?
Planit · 2026-05-24 · via DEV Community

凡行事之软件,多囿于幻境.

幻境者,谓行事之际,WiFi无碍,志愿者各持专帐,器物专一,门庭无虞也。诸大平台,若Eventbrite、Whova、Cvent,皆循此臆断而构。其枢在服务器,万务皆经云中。若连接断绝,则系统停歇。

吾尝观此假设于实境败绩。众流阻塞。吏卒转用 WhatsApp。或取簿记之表。本欲助人者反为人所规避。

此乃吾构 PlanIt 以解之弊。


非其本象

会务软件之业早有决断。其决曰:会务者,首在注册与营销之弊。故设注册之页,票务之售,与会者之系,赞助者之台,及电邮之策。

此实为弊,然非致会于当日而殒之弊也。

一日之会,败于协合之失。签到处滞涩,盖器物失联之故。二门之司事,信息殊异。一志士欲登,而会者忘为其立户。众之析疑,散于三WhatsApp之线。

未尝有软件为此层。吾乃为之。


计画之实,何也?

PlanIt乃一免费托管之活动运营平台。非欲为Eventbrite,实欲为协理之层,使当日之事得以成行。

此意于实践者何如。

线下优先签到

凡运行PlanIt之器,皆于本地缓存与会者之全列。若网路不通,则签到无碍。扫描之事,暂列于本地,待网路复通,自能同步。冲突之解,可处复门之重扫。

此非远期之志,亦非将来之制也。实乃系统之基石,盖因吾设身处地,预设其络绝,非期其永固也。

基于PIN码之职司认证

众平台皆以为员有私邮,有暇立凭,而后行事。然实非此理。志士当日而至,器物递于众手。须有者立检,速扫,不逾卅秒。

PlanIt以PIN码为凭,使员工登入。组织者预先为员工设帐,授以用户名与PIN码。团队任一成员可取任一设备,输入其PIN码,立时可用。无需邮件。无需重置密码之流程。无摩擦,而摩擦之时,其价最昂。

此乃POS系统之运作。此乃仓库扫描器之运作。此乃医院轮班终端之运作。此非活动软件之运作,然其当如是。

WebRTC 推至通话

重大活动之际,协调之失多因沟通之失。若门庭有变,则组织者须即时达诸团队,不须离检视之界面,不须启别之应用,不须恃蜂窝之覆盖。

PlanIt内置WebRTC技术之按讲系统。员工持键而语,诸接续之器实时得闻其声。此系统与运作之境相融,无需别设平台.

吾未闻他之免费会务器具,有此功能者.

诸器实时同步

每一签到,即时显于网中诸器。事毕无复校之需。一处所见,与他处无滞。系统使诸连器同刻一共享之运态。

批量CSV导入及QR码

逐邀五百之众,非为常法。PlanIt可批量导入宾客于CSV,每客皆得独有之码,系于其籍。役者于门扫描,立时验之。宾客无需帐户,无需应用,亦无需登录。

座次图与场域管理

拖拽式座位图构建器,实时分配。员工可于入住时精准知客位。组织者可于会中实时移客。


此架构之异

标准会务SaaS之貌若此:
浏览器 / 应用
|
中央REST API
|
云端数据库

万物系于恒通,权柄在焉,认证归一。

PlanIt则与此相近。
器物本地处之状态
|
同侪/设备同步
|
云 reconciliation

每器各具半自主。云乃调合之层,非真源唯一。此乃根本异构之思,更易系统于实境之态。

其架构近于多人游戏或实时协作之器,远非传统SaaS仪表盘。此非偶然。事件乃实时分布之系统。软件当如是反映之。


其无所为 __JHSNS_SEG_136869e3_46__Plan无票务。无处理支付。无赞助管理,无电子邮件营销,亦无付费事件之公开发现页面。

此乃有意之阙,非疏漏也。其物主于运筹协理,非预事宣导。增付讫之务,非增其本用之善也。


今之所处

PlanIt已布,且无费于planitapp.onrender.com。无订阅之费。无按人计之费。无客之限。

日方早。此界面可用,然未臻精工。其同步之理甚固,然未历大战。有粗疏者,有未睹者。

吾独为之。年十三。始于二二五年冬。

吾非欲以此文炫人,实因事之有实,类之有阙,欲使办真事、涉真繁者知其存在,并告吾其弊。

若主事者,可试之。若为匠者,无论用否此物,其构皆可深思。若尝立于会场之入口,睹签到之制失灵,而众列于后,则尔已洞悉吾建此之由矣。
