Apprise vs Rspamd
A side-by-side editorial comparison of Apprise and Rspamd — release velocity, themes, recent moves, and the top alternatives to consider.
Apprise vs Rspamd: at a glance
What is Apprise?
Apprise 2 is out: notify() returns a result object, and 2.1 takes the catalog to 170 services.
Apprise, the Python notification library, shipped v2.0.0 on 26 September after closing out the v1 line. notify() now returns an AppriseResult with per-service status, including new PARTIAL and TIMEOUT states, and v2 adds template variables for secrets, tag priorities with escalation, retries, timeouts and multiple body formats per service. v2.0.1 fixed markdown handling and v2.1.0 added 12 services, for 170 in total.
What is Rspamd?
Rspamd 4.2 hardens its parsers and ships memory-safety fixes three releases running.
The 4.2 line opened in September with a public suffix lookup replacing the old TLD tables, attachment content extraction for SVG, OOXML and DOCX, and one scheduler over the symbol dependency graph. 4.2.1 fixed critical memory-safety bugs including an HTTP heap overflow. 4.2.2 added wallet-address detection across twelve named currencies and changed MIME digests. 4.2.3 stopped trusting ARC forwarders whose seal fails and merged duplicate RBL queries, so a rule scores once per matched value.

Apprise
5.0COMMS
Apprise 2 is out: notify() returns a result object, and 2.1 takes the catalog to 170 services.
◆ Current state
Apprise, the Python notification library, shipped v2.0.0 on 26 September after closing out the v1 line. notify() now returns an AppriseResult with per-service status, including new PARTIAL and TIMEOUT states, and v2 adds template variables for secrets, tag priorities with escalation, retries, timeouts and multiple body formats per service. v2.0.1 fixed markdown handling and v2.1.0 added 12 services, for 170 in total.
◆ Where it's heading
The v2 break was about making delivery observable and controllable, building on the weighted tags of v1.11. Since then the project is back to its usual rhythm of community service additions and fixes, with v1 maintained on a separate branch.
◆ Prediction
Expect v2.x releases of the same shape, new services plus fixes, with more v2-era adoption fixes for embedders moving off v1.
Rspamd
5.0COMMS
Rspamd 4.2 hardens its parsers and ships memory-safety fixes three releases running.
◆ Current state
The 4.2 line opened in September with a public suffix lookup replacing the old TLD tables, attachment content extraction for SVG, OOXML and DOCX, and one scheduler over the symbol dependency graph. 4.2.1 fixed critical memory-safety bugs including an HTTP heap overflow. 4.2.2 added wallet-address detection across twelve named currencies and changed MIME digests. 4.2.3 stopped trusting ARC forwarders whose seal fails and merged duplicate RBL queries, so a rule scores once per matched value.
◆ Where it's heading
The input-hardening walk from 4.1.x has become line-wide policy: limits on untrusted UCL, bounded PDF and decompression work, and HTML parsing that matches browsers so content cannot hide from the scan. Detection moves the same way, into what attachments and hidden text actually contain. Point releases keep carrying incompatible changes to digests and scoring, so operators need to read the notes on every update.
◆ Prediction
Expect more browser-parity fixes in HTML and URL handling, and attachment extraction beyond the SVG and OOXML set. The planned flip of allow_file_and_shm_inputs to false does not appear in the 4.2 notes, so it remains the breaking change to watch.
