Keep the simple HTML endpoint while leaving containers, SQLite backups, Mailgun credentials, monitoring, and upgrades behind. Form Plume adds managed delivery, free uploads, broader spam defenses, and several automation paths.
Side by side
Formlite and Form Plume solve the same frontend problem but make opposite operational promises. Formlite gives you source code, a container, and direct data ownership; Form Plume gives you a maintained service. The comparison below treats self-hosting as a genuine strength while showing what the operator must supply after deployment.
| Decision point | Form Plume | Formlite |
|---|---|---|
| Hosting and ownership | Fully managed form backend Form Plume runs the service, database, updates, and delivery infrastructure. | Self-hosted only MIT-licensed source runs in your own Docker environment with your data under your control. |
| Cost model | 500 submissions free; $12 Pro Managed hosting is included; Pro raises capacity to 10,000 monthly submissions. | No Formlite license or SaaS fee You still provide hosting, a domain, operations, and any Mailgun usage. |
| Deployment and data | Create an endpoint and start collecting There is no container, database volume, runtime, or production upgrade path to maintain. | One Node container and one SQLite volume The operator builds or pulls the app, mounts persistent storage, configures its origin, and owns backups. |
| Email notifications | Managed notifications included Receive new submissions without bringing an email API account or managing sending credentials. | Mailgun account and credentials required The operator supplies an API key, sending domain, sender address, and US or EU Mailgun region. |
| Signed webhooks | 1 on Free; Unlimited on Pro Managed signed destinations connect submissions to production workflows before the first upgrade. | Self-hosted HMAC-SHA256 webhooks Each destination has a secret; the current implementation signs JSON and applies a ten-second request timeout. |
| Spam and origin controls | Layered prevention plus recoverable quarantine CAPTCHA choices, honeypots, time traps, rate limits, domain controls, blocklists, email hygiene, and reviewable spam. | Honeypot and domain allowlist The submission endpoint silently accepts filled _gotcha fields and rejects origins outside the configured list. |
| Files and submission formats | 100 MB of uploads on Free HTML forms and fetch requests can collect fields and attachments, with 10 GB of storage on Pro. | HTML form data and JSON fields The current endpoint accepts form and JSON bodies but skips File values while parsing multipart data. |
| Integrations and operations | Native apps plus broad automation routes Use Slack, Discord, Sheets, email tools, Zapier, Make, MindCloud, or arbitrary signed webhook targets. | Mailgun email and generic webhooks Flexible HMAC webhooks can reach other systems, while monitoring and failed-delivery handling remain with the operator. |
Where Form Plume pulls ahead
Formlite removes SaaS licensing and keeps data on infrastructure you control. Form Plume removes a different class of cost: deployment, database care, delivery configuration, spam operations, and the maintenance that continues after a ten-minute install.
Formlite packages its application cleanly, but someone still owns uptime, TLS and DNS, image updates, secrets, logs, incident response, SQLite durability, and restore testing. Form Plume turns those recurring responsibilities into a managed endpoint.
Formlite sends notifications through Mailgun, requiring an account, API key, verified sending domain, sender identity, and region selection. Form Plume includes managed notifications, so a new form can deliver useful results before an email stack is provisioned.
Formlite covers stored submissions, Mailgun notifications, and HMAC webhooks. Form Plume adds attachment storage, autoresponders, recoverable spam, native destinations, automation ecosystems, exports, and API access without turning every addition into self-hosted engineering work.
Choose by situation
Developer who requires local data custody
Formlite
Its MIT-licensed source, SQLite database, and self-hosted-only model keep the application and every submission on infrastructure you choose.
Marketing site without an operations team
Form Plume
A managed endpoint, notifications, spam controls, and monitoring avoid creating a service that the marketing launch must keep healthy.
Application form collecting attachments
Form Plume
Uploads and storage are supported directly, while Formlite's current multipart parser skips file values.
Homelab or controlled internal deployment
It depends
Formlite rewards teams that enjoy running Docker and backing up SQLite; Form Plume is simpler when availability and delivery matter more than server ownership.
FAQ
Choose Form Plume when you want the endpoint experience without owning another production application. It manages hosting, notifications, file storage, spam review, delivery infrastructure, integrations, updates, and scaling while your frontend continues to submit ordinary form data.
Yes. Formlite's official site describes it as MIT licensed, open source, and self-hosted only, with no Formlite SaaS subscription. Running it can still involve infrastructure, domain, backup, observability, and Mailgun costs. Form Plume instead offers a managed Free plan and paid capacity when traffic grows.
No. Formlite is the appropriate choice when deploying the form backend on infrastructure you control is a hard requirement. Form Plume is a hosted service designed for teams that prefer the provider to operate the database, delivery pipeline, security updates, and runtime.
Usually. Both products accept normal HTML form submissions through a unique endpoint. Create a Form Plume form, replace the action URL, preserve field names, and test the success state, notifications, allowed domains, and webhooks before taking the Formlite container offline.
Formlite stores submissions in a SQLite database whose path defaults to /data/freeform.db. Its Docker setup mounts that directory as a persistent volume. This makes the data directly yours, but it also makes backup frequency, off-site copies, corruption checks, and restore testing your responsibility.
Formlite sends through a Mailgun account configured with your API key, domain, sender address, and region. Form Plume includes email notifications as a managed feature. That removes provider setup for a basic inbox, while higher Form Plume plans add autoresponders and custom sending options.
Yes. Formlite's current source signs JSON payloads with HMAC-SHA256 and sends an X-Freeform-Signature header. Form Plume also signs deliveries, includes one webhook on Free, and provides unlimited signed destinations on Pro for managed automation workflows.
Formlite implements a practical honeypot and per-form origin allowlist. Form Plume goes further with multiple CAPTCHA options, time traps, rate limits, blocklists, email hygiene, adaptive filtering, domain controls, and a recoverable quarantine for reviewing false positives.
Not in its current published submission handler: multipart requests are accepted, but File values are skipped when fields are parsed. Form Plume includes 100 MB of upload storage on Free and 10 GB on Pro, making it a better fit for applications, briefs, and document intake.
