What is Subsplash?
Subsplash Giving now syncs donations and people with Planning Center.
Subsplash runs giving, media, people and workflow tools for churches. In November it made Dashboard Home a single view across all its products, then on 10 November connected Subsplash Giving to Planning Center: transactions sync one way on a schedule or on demand, profiles sync both ways, funds are mapped, and each sync produces a report with flagged items staff can fix themselves.
What is Fonoster?
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
Subsplash vs Fonoster: editorial side-by-side
Subsplash
5.0COMMS
Subsplash Giving now syncs donations and people with Planning Center.
◆ Current state
Subsplash runs giving, media, people and workflow tools for churches. In November it made Dashboard Home a single view across all its products, then on 10 November connected Subsplash Giving to Planning Center: transactions sync one way on a schedule or on demand, profiles sync both ways, funds are mapped, and each sync produces a report with flagged items staff can fix themselves.
◆ Where it's heading
Recent work focuses on the church office's admin load: notes, multi-select, reconciliation, a unified home page, and now integration with the people database many churches already use. Subsplash is positioning Giving to work alongside Planning Center rather than requiring churches to replace it.
◆ Prediction
Further Planning Center links, such as events or groups, are plausible, but the entries do not indicate which comes next.
Fonoster
7.5COMMS
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
◆ Current state
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
◆ Where it's heading
After a quick run of voice-AI options, Fonoster has turned to what a hosted service needs before paying customers rely on it: legal pages, billing correctness, webhook debugging and account deletion that actually removes data. The cadence stays daily and the changes stay incremental.
◆ Prediction
More account and billing lifecycle work is likely next, since v0.57 adds a billing test case and deletion rules in the same release.
