Frill vs Plain
A side-by-side editorial comparison of Frill and Plain — release velocity, themes, recent moves, and the top alternatives to consider.
Frill vs Plain: at a glance
What is Frill?
A customer-feedback and roadmap tool hardening steadily for enterprise buyers.
Frill is a customer-feedback, roadmap, and changelog platform shipping monthly release notes. The past year skews toward enterprise readiness — Okta and Microsoft Entra SSO, EU data residency, CSP security, and an expanded Ideas/Comments API — layered on top of its core boards, surveys, and boosted announcements. Development is broad and steady rather than concentrated on any single bet.
What is Plain?
Plain turns Sidekick from a drafting assistant into an agent that acts
Plain is a customer-support platform building an agentic layer — 'Sidekick' — into the core thread workflow. Recent releases moved Sidekick from suggesting to acting: it can take actions across connected tools, start working proactively the moment a thread matches a workflow, and it now answers in Slack. The surrounding plumbing (scheduled workflows, thread fields via the chat widget, machine-user API links to Linear) is all in service of more automation.

A customer-feedback and roadmap tool hardening steadily for enterprise buyers.
◆ Current state
Frill is a customer-feedback, roadmap, and changelog platform shipping monthly release notes. The past year skews toward enterprise readiness — Okta and Microsoft Entra SSO, EU data residency, CSP security, and an expanded Ideas/Comments API — layered on top of its core boards, surveys, and boosted announcements. Development is broad and steady rather than concentrated on any single bet.
◆ Where it's heading
The product is climbing upmarket: data-residency options, enterprise SSO, and API depth are the throughline, while the feedback surface itself widens with surveys, polls, and configurable announcements. Nothing in the recent cadence signals a category shift — this is a maturing tool filling gaps competitors already cover. The pace is consistent but incremental.
◆ Prediction
Expect further enterprise hardening — deeper SSO, compliance, and API/webhook coverage — plus continued small additions to widgets and announcements rather than a new product line.

Plain turns Sidekick from a drafting assistant into an agent that acts
◆ Current state
Plain is a customer-support platform building an agentic layer — 'Sidekick' — into the core thread workflow. Recent releases moved Sidekick from suggesting to acting: it can take actions across connected tools, start working proactively the moment a thread matches a workflow, and it now answers in Slack. The surrounding plumbing (scheduled workflows, thread fields via the chat widget, machine-user API links to Linear) is all in service of more automation.
◆ Where it's heading
The arc points to autonomous, workflow-driven support: AI that investigates, summarizes, drafts, and executes before a human opens the thread. Each release widens either Sidekick's reach (Slack, connected tools) or the triggers that set it off (workflow conditions, schedules), steadily shifting the human role from doing the work to reviewing it.
◆ Prediction
Expect deeper Sidekick autonomy — more action types and likely approval or guardrail controls — plus more workflow triggers that launch automation without a human in the loop.
