SnapGene
Molecular cloning on a Mac starts with a plasmid map you can read, then a simulated reaction that flags design mistakes before oligos are ordered.
Maps, features, and the Actions menu
Open a SnapGene document, a GenBank record, or FASTA and you are looking at one molecule in two views. Map view draws it as a circular or linear plasmid with features, restriction sites, primers, open reading frames, and translations. Sequence view shows the same nucleotides with those marks inline. A curated common-features database can drop in promoters, origins, resistance genes, and tags; you can also select a span and add a custom feature, then hide enzymes or labels until the ring is readable. The vendor hardware note asks for at least a 1440x900 display, 1 GB of memory, and about 250 MB of disk.
Planning happens in the Actions menu rather than by editing the map as a drawing. Restriction cloning, Gibson Assembly, Gateway, Golden Gate, In-Fusion, NEBuilder HiFi, TOPO, TA or GC cloning, and PCR each open a guided dialog with defaults you can change. The preview shows how fragments are supposed to join and points out problems such as missing sites, methylation, or phosphorylation that would waste a transformation. Each edit and simulated procedure is written into a graphical history inside the file, so a colleague who receives the document can see how the construct was assembled, not only the final bases.
Reads, gels, and a multi-file folder
The Tools menu is the check after the plan. Align to Reference compares sequencing reads with the simulated construct. Pairwise and multiple alignments can run through Clustal Omega, MAFFT, MUSCLE, or T-Coffee, and CAP3 can assemble Sanger reads into a contig. An agarose-gel view lets you set lanes, agarose percentage, run time, and a ladder, then draws the bands you should expect, including PCR products from selected primers. That picture does not replace a real gel or a sequencing core. Selecting several files in a project folder opens a sortable metadata table; enzyme and primer tooltips carry extra detail; Sanger traces use the same window as other sequences, with a full-height option.
Seats, sign-in, and the disk image
Download the disk image from a SnapGene account, open it, and drag the application into Applications. Licenses purchased on or after 12 November 2024 activate with email sign-in; older purchases still use a registration key. Academic pricing is $350 per user per year, corporate pricing $1,845, and a qualifying student subscription is $149. A permanent academic seat is $3,000 and a corporate seat is $11,500, single-user, with no later upgrades. If a subscription expires, the app switches to Viewer mode: you can still view, annotate, and share sequences, while most simulation commands are disabled. A separate free Viewer is available for people who only need to read maps. The build is universal, native on Apple Silicon from M1 through M5 and still compiled for Intel, and the support table lists macOS 12.0 through 15, which the vendor labels Monterey through Tahoe. SnapGene 8.2.3, released 25 August 2026, is that download; its Addgene plasmid importer no longer signs in inside the app and opens the Addgene website instead.
Show full description Pros & Cons Show details
PROS
[*]Map and sequence views stay locked to the same file, so a feature hidden on the plasmid ring disappears from the nucleotide text as well.
[*]Actions walks through restriction, Gibson, Gateway, Golden Gate, In-Fusion, NEBuilder, TOPO, and TA or GC cloning and marks design flaws before oligos are ordered.
[*]Procedure history is saved inside the document, which lets a lab mate open the file and see how the construct was built.
[*]Align to Reference, Clustal Omega, MAFFT, MUSCLE, T-Coffee, CAP3 contig assembly, and an agarose-gel preview cover the usual checks after a simulation.
[*]A universal Mac binary runs natively on Apple Silicon from M1 through M5 and still launches on Intel Macs inside the published macOS 12 through 15 window.
[*]Course use can be free when an instructor provides seats to a class, and a separate Viewer app can open maps without a paid license.
CONS
[*]Corporate pricing is steep next to the academic rate: $1,845 per user per year, or $11,500 for a permanent seat that never receives a newer version.
[*]An expired subscription drops the app into Viewer mode and disables most simulation commands, so the file still opens but the cloning tools do not.
[*]Published macOS support for the 8.2 line stops at macOS 15, and the vendor does not guarantee that this build will keep working on later system releases.
[*]Import Addgene Plasmids no longer logs in from inside the app; version 8.2.3 sends you to the Addgene website because the old integration does not match their sign-in.
[*]Anonymous usage data can leave the machine, and the 8.2.3 notes record that this tracking had switched itself back on after restart for some people.
[*]The window assumes a 1440x900 display, so maps, traces, and the side panel feel cramped on a smaller laptop screen.
[*]Nothing here drives a thermocycler or a sequencer; a clean simulation can still fail once the DNA is in a tube.
[*]Permanent seats are single-user only, with no group discount, which makes them a poor fit for a shared lab computer.
What's New in 8.2.3 Show details
[*][geo_loc_name] - Adds support for the /geo_loc_name GenBank qualifier so location metadata can travel with the record.
[*][transcript_id] - Extends support for the /transcript_id GenBank qualifier on annotated sequences.
[*][OsTIR1 feature] - Adds OsTIR1(F74A) to the Common Features Database.
[*][Signal peptides] - Corrects several signal peptide entries in the Common Features Database.
[*][Gateway fragments] - Fixes a bug that could drop features during multi-fragment Gateway cloning reactions.
[*][Addgene import] - Opens the Addgene website instead of signing in inside the app, because the old login no longer matches Addgene's requirements.
[*][Updater cancel] - Fixes the updater getting stuck after a download is cancelled.
[*][Tooltip layering] - Fixes tooltips drawing behind other menus.
[*][Alignment settings] - Fixes a crash that could occur when opening alignments after default settings are saved.
[*][Damaged alignments] - Fixes a crash when opening some corrupted alignment files.
[*][Large alignments] - Fixes a hang while working with large alignments.
[*][Usage tracking] - Stops anonymous usage tracking from turning back on after a restart for some users.
[*][Usage data crash] - Fixes a crash that occurred while sending anonymous usage data.
